I updated the spreadsheet to make it a bit more explanatory. After not looking at it for awhile, I had a time figuring it out. I hope this helps. Print them both out and tape together to make one work sheet. 280Z Valve Adjustment Chart v3.pdf

I measured my original bumper and it measures the same as @jfa.series1. I also drew a line on the new bumper that traced the rear of the car. When the line was complete, they also matched your measurements. That said, I have a relative that can trim the excess off the inside of the bumper and everything should line up. It may take a week or two, so I'll report back when it's done. Thanks to all for your inputs.

@jfa.series1one last question (I hope). What is the width of the bumper on each end and in the middle? Mine is about 2.5” on each end where it joins the corner piece. and about 2.75” in the middle.

My bumpers are from Vietnam too. Although I did need to add shims, I think I've got it looking pretty good. I must say that there is more gap on each side than there is in the middle, but it's not real noticeable. After I get it tightened up tomorrow, I'll take some pics. @jfa.series1Does yours have more gap between on the ends than in the middle, OR is it even all the way across? I can put my finger tip between the bumper and car on each side, and about half that in the middle.

I don't have any pics from that angle. I have the bumper off the car.

The reason for my question is mainly that the bumper, when installed, slightly touches the body in the middle (dead center) of the car. I thought before I add shims, I'd like to be sure it's installed correctly.

Looking at the pic again, it appears the bottom is tilting outward. Meaning the bottom is further away from the body than the top is. Any thoughts?

Thanks @SteveJ! Is there any sense of tilt to the bracket? There doesn't seam to be any in your pic.

I tried both directions, but neither was obvious. I'll look more closely as @jpc3006 stated. I'll report back tomorrow.

Does anyone know how the rear bumper brackets are mounted? I have two sets and both sets have one side taller that the other. There's also a slight tilt from front to back. The pic shows the taller side clearly, but the tilt is a bit harder to see. The tilt is from section just below the DATSUN letters touching the manual toward the front of the pic. I guess an answer could be stated something like - when mounted, the taller side outward (Or inward) and the bottom of the bracket tilted inward (Or outward).

I'll try tweaking the heat shield a bit and report back. Regarding the return springs, I have them rigged with a piece of wire to put tension on them. It would definitely make my life easier if I can get the heat shield corrected.

I have headers on mine. I must say that I haven't tried to hard to put in place yet. When I bought the header, I really didn't put much thought into which one to buy. I wish I would have don'e a bit more homework. Is it safe to assume that I don't want the heat shield touching the header after it's installed?

@jfa.series1what header is that on the motor pic you posted above? My header won't let me install my carb heat shield.

Thanks everyone...I'll keep the hose

Do most owners plug the PCV valve and put a breather on the crankcase, OR keep it original with the hose?

@siteunseen what is MSA? I've seen it many times, but never asked.

I called O'Reilly today. They submitted a Service Request to Cardone for a distributor rebuild. I figured I may as well have them submit one for a brake booster rebuild too. It appeared to be one of the first requests they submitted, so he had no idea how long it would be for them to get back to me.

Thanks, I'll try O'Reilly and report back

Is there any place I can buy a rebuilt distributor for 240Z?

What is the large tube sticking out just below the front carb? does it connect to the balance bar? If so, do they have to be connected with a hose? can they be plugged? can they be left open?

thx

Thank you for putting it in simpler terms. I can’t believe the knucklehead configured it that way.

I think I have a mixed up fuel line system, but want to verify. I had someone install an electronic fuel pump and this is what they did. Below are the questions I have: 1. Does the input to the fuel filter connect to the shorter (more rearward) fuel line? 2. Does the output of the fuel filter connect to the bottom rail of the fuel rail? 3. If correct above, then what does the top fuel rail and longer (more forward) fuel line do? Here are a description of the pics I attached: The diagram shows the way it’s configured. The fuel filter is connected to the shorter (more rearward) fuel line along the frame, and then connects to the top rail of the fuel rail. The next pic shows how he connected them with two filters. That’s what tipped me off to an potential issue. He did that to accommodate the different sized pipes from fuel filter and fuel rail. d The next pic shows the shorter (more rearward) line connected to the fuel filter.

That's strange...It came up on my "Activity in Last 24 Hours".

It definitely sounds like a vacuum leak. I'm troubleshooting very similar symptoms, but mine appears to be the carb shafts. Someone should be able to chime in, but I would guess you could eliminate the brake booster by plugging the booster hose to see if the problem goes away.
