I am attempting to tighten the shift linkage on my early '71. I had some new nylon bushings in "stock" so I thought I'd use those. When I got to the linkage, there was no match with the bushings. So, I think I have a Type A transmission. Can someone tell from the picture below? Also, how do I fix this linkage so I don't have to stir to find the gear? Just a different bushing? Thanks

We purchased this resurrection project knowing it had been sitting since 1996, and the sit time was not too friendly to our Z. Besides being rusty in the pulley grooves, I am a bit concerned about the rubber binding material on the balancer. The ones I have found do not look like the original and the diameter specs listed do not match mine. There are a few specialists rebuiding the balancers with new bonding processes. Any suggestions from the Z experts will be greatly appreciated. Based on the number of harmonic balancers we sell at our parts store for much newer vehicles, my previous belief of them being a part that never goes bad, has been erased. Being over 40 y…

Hey everyone, I've combed through the archives looking for directions on swapping out the speedo pinion gear, and I found some information but I'm a bit nervous taking on this task as I don't want to wreck anything (cable, gear, etc.) as the parts are so hard to find. I have a 1983 5-speed in my 1971 Datsun, and I finally finished the 4.11 LSD diff (which works great). The speedo gear I have now is 20 tooth, and it's about 10% off, so I'm moving to the 21-tooth version (they don't make the 22 anymore). (FYI, when I contacted Nissan to order the part, there were only 2 left in the country and it's being discontinued, so if you need one, now's the time to get it!) My plan…

I'm swapping out my wide ratio 5-speed for a close ratio transmission. I'm curious to know what, if anything, I can tell about the condition of the replacement transmission prior to installing it. I'll have a choice between a number of loose transmissions and obviously want to make the best choice I can.

I Removed the 8 12mm bolts from the tail housing, I also removed the little pin with the c clip. What do I have to do next to separate the tail section? The striker arm now moves out about an inch or 2 inches. Sent from my iPhone using Tapatalk

I have had a plan to swap out the non-original motor in my car with the original, correct motor at some point and decided it was time to do it. I have been very happy with how the motor has been running, just want the number correct motor in it. First little problem I found was a broken cam oiler tube. This is very common and as I had checked the valve settings this spring and saw no problem then it is a fairly new problem. I have another oiler to replace it. The next problem was a bit disappointing. It seems I have developed a crack in my E30 non-emission exhaust manifold. The second photo shows the pattern of the exhaust on the back side of the heat shield. Now…

Trying to do some research during my tear down. Have gotten a lot of info here, but have a few questions; I have a 73 Z with auto trans but will be changing to manual on the rebuild. I have a spare engine and trans from a 72 Z. I'll be using that trans. I need to clarify some of the wiring. On the auto there are two wires on the left side of the trans (black wires). From what I can tell these are for the kick down solenoid and will not be needed on the manual trans. On the right side of the auto are the four wires , 2 for the inhibitor switch and 2 for the back up lights. I know the inhibitor wires need to be connected together so the car will start with the manual…

So I'm out driving around today, just minding my own business... All of a sudden, out of the blue, it starts running exceptionally poorly. Somehow (still not sure how), I managed to limp it about five miles home. Get home and start the troubleshooting. It's completely missing on the rear three cylinders and front firing out the intake like the timing is way off. So, what can cause a complete miss on the rear three cylinders and run like turds on the others? ECU? Nope. That's not it. Dropping resistor? Nope, not it either. Bunch of lash pads fly out? Nope. "When you have eliminated the impossible, whatever remains, however improbable, must be the truth.…
