About the only thing I’m putting on the bottom of my Datsun’s now is a pro quality 2-part “truck bed liner” like Raptor. It has proven itself on the bottom of several heavily driven cars in my sphere of influence…. As with anything you apply to your bottom, proper prep and attention to detail are the key to staying stuck for a long long time. My first experience with this stuff in the bed of my various ford 1/2 tons, and with all the scrap metal and datsun junk I have abused those boxes with the ONLY damage I have ever done to the coating is with a single small chip that I caused with an sharp engine block corner crashing into the deck one day when “putting” (more like tossing…) it back there. With the current truck we are 7 years in and the coating looks new, other than not being shiny and black anymore.

Yes this is always an option. I haven’t measured it, but the total adjustment in the two slots on the dizzy base seem to be about the rotation distance between the 6 towers. The only issue is assigning wire lengths that “fit” well with your new dizzy ‘TDC” position for each plug.

Datsun stud pattern is 4 x 114.3mm. What bolt pattern are the wheels you’re looking at? +25mm wheels will require spacers to clear the tire away from the strut, maybe 15mm (5/8) is enough spacer.

I can beat totalZ and ebay pricing. Send me PM and we’ll discuss

Glass beads will work, as will a wire brush. Brass or SS. Cleans up aluminum very nicely. Then an oil based sealer like Gibbs to preserve the finish. I’ve even used the cast aluminum caliper paint from VHT.

How many times have we heard “the power is in the head”. Still true. Cam, lift, porting. Make’r flow like a hurricane!

Here is my tool, just for completeness and give others ideas.

Flat blade screw driver and hammer has always worked for me. Tap one tab, then next, it comes off. I did make a tool to help, which it does, especially when the tank is still in the car. Based on a short 2” steel pipe nipple that I welded little tabs on that hit on those four little tabs. Then added a bar and 17mm nut welded in the center to put a socket or wrench on. Great if you have a welder. Interesting that the Honda ring is so similar. Good find.

You know, we all do it, browse through some marketplace, ebay, craigslist, Kijiji, looking for Datsun goodies, sometimes you find something interesting and you put it in your shopping cart for later. Gives you a chance to ask that eternal question, “Need” or “Want”…. Makes you feel like you’re in control of your purchases. Right… Anyway. Well I’ve done that on ebay lately, put a couple if items in my cart for “later”, A headliner for my latest 510 project, some key blanks for Z locks, etc. Both items were simple purchase, not auctions. Well, the key blanks were in the cart first and by themselves for about a week when I get this un-expected notification from ebay that the seller has given me an a special discount offer of 10% off if I agree to buy in the next little while. Interesting! Decided not to push the button just yet. Then after adding the head liner, about 3 days later I get a similar message about a discount offer of 11%! This one I jumped on, as I was just waiting to decide who to buy it from. (Goliners, respected well know Datsun headliner vendor, not a scam) So next time you want to buy something on Ebay, and you can wait a few days, put it in your cart and let it “ferment” there for a few days and see what happens! Maybe you’ll get a discount too!

The thing that freaked me out was the day I discovered the hatch lock striker bar isn’t in the center of the slam panel. The release button up on the hatch deck is in the middle, but not the actual catch Sometimes we assume symmetry where none exists.

Never seen a published solution for using an extrusion on an SU manifold, but I bet it’s been done. Heat wise, I’d be tempted not to mount the rail to the head. There are plenty of un-used mounting points on the balance tube that I would likely press into service. The stock fuel rail return line has a tiny orifice hole in the tip where the 3/16 hose gets clamped on, this is the stock pressure regulation. I’m hoping you plan on running some sort of regulator on your system on the return side of your rail.

Or seriously, some Killmat or Dynamat foil with butyl backing sound insulation sheeting provides excellent adhesion and permanent seal. Put lots of it down while you’re at it.

Wasn’t there some big Z shin-dig going on earlier this year in Colorado Springs? Some little party called ZCON or something? Must be a few Z people hiding under the bushes you could rustle up.

The “thing” on the left looks to me to be an aftermarket temperature switch, the kind of thing you use to trigger an electric fan on the rad. When the temp gets to the right temp that spade terminal is connected to ground, which you use to trigger a relay to turn on the fan. The 1/4 spade connector is the type of thing I’d expect to find on an aftermarket switch of that type.

Sean I have a bunch of these. I’ll send you a good one. Send me a PM and we can discuss. I’ve had several that stick like yours, it was a pain to take it apart and file in the just the right places to free it up. It was also very unclear as to how this stickiness developed in the first place.

Start by grinding away the flange on that control arm mount saddle to make more room. There is tons of material that will have no effect on strength if removed. Then loosen all the exhaust mounting points and see if you can get another 1/4” of clearance.

I discovered this place quite a while ago and have shared it in the past. Has an amazing array of tidbits for just this type of construction. I’ve bought tons of the 8mm x M5 ball ends and various linkage parts to build carb and throttle cable goodies. They also have larger spherical rod ends to build bigger things.

Just ordered it from Amazon.ca. Pricey at $205 CAD but worth it. No more chipped fins…..

I’ve struggled with enough of these nasty corroded on drums to take the plunge with this puller. Thanks for the part number. Just finished another session of MAP gas heat and 2lb sledge blows that always ends up with drum damage to some extent. While I’m here, I’ll also share a related issue we all need to check each time we get one of these nasty super-stuck drums off. On the second last 71 I worked on, someone had gotten the drums off for me, (thank you thank you thank you) but for the life of me I could not get them to go back on and sit flush. Once I studied them a bit, it was obvious. The first 1/8 inch of the inner circle of the edge of the aluminum drum had actually come off (more like fallen apart) and was stuck to the face of the stub axle around the raised center section! Because that material was un-even, the drum only when back on flush if you got the clocking right so the bits (on the hub) and gaps (on the drum) lined up again! I had to chip that hard aluminum oxide residue off of stub axle face all around the hub center with a chisel. So if your struggling with rear wheel vibration, maybe your drums are sitting tight to the stub axles. Oh! And another hint, this one gleaned from the 510 world. Their drums have two or four M8x1.25 threaded holes in the drum face between the studs. You just thread in some bolts and these press on the stub axle face and pop the drum right off! Technically you could drill and carefully tap some holes in a stuck Z drum (with a bottoming tap) and use the bolt trick, but maybe do this to new drums before you put them on to prevent any and all future grief. Here is a picture of a new aftermarket 510 brake drum from Rock Auto. Note the extra pair of holes.

There stuff is amazing and accurately done. Got a shed full of it. Almost makes me want to take on one more major rust repair challenge. There is this somewhat rusty 71 in storage that I should.... no, yes, not, yes. ah dang it... And more exciting, is that they are starting to do 510 stuff as well! Be still my beating heart
