@Route66 They aren’t repos, they are awesome fenders, just 280 fenders. Very modest modification needed for perfect fit. You’ll need a body guy with a welder to move the little clip for the inspection panel to snap in……an easy job, and once you bolt it up, a slight mod to get the seams perfect……all zero sweat. @zspert is the expert to comment on the mods…..you can see the perfect result on my 71.

Nice Zed, it's a famous number often played, this one is also a good choice... OZZY OSBOURNE - "Mama, I'm Coming Home" (Official Video) - YouTube

Newer but pretty cool!

It seems that's what you've been doing for the last decade and really aren't any closer to a solution than you were when you first recognized the problems. Unless you have a strong emotional tie to your Z, I suggest moving on to another car that you can enjoy driving with confidence that it will run well and get you where you want to go and back home. Just a suggestion that could make your life less complicated and more enjoyable. I once had a '74 Porsche that I never drove farther from home than I cared to walk back. I knew several AAA tow truck drivers by their first names. I was happy and relieved to finally sell it and eventually bought another that I've owned for 32 years.

He didn't but these guys did.

@Nils Ya, when you press the switch it's supposed to flip into the other position. It sounds like you have a similar issue to what I had originally: I could depress the toggle, it would temporarily switch to the other side, but once I released the switch it would reset back to the original position. Yours sounds a little worse as it isn't even able to temporarily switch. I forget which colors correspond to which, but power comes in through the center connection, and then goes out through the connections on the left or right - one for high beam, one for low beam. Ie, we'll just call the connections 1, 2, and 3, with 1 being high, 2 being the center, and 3 being low. 1-2 would trigger high beams, and 2-3 would trigger low beams. You can test that with continuity. You should never have continuity between 1 and 3. @fredrick that's a spring and a brass cap. It sits in a circular opening in a rocker inside the actual switch housing. The piece is held into the plastic via a roll-pin and is the only part I didn't remove when disassembling the whole thing (I didn't think there was a chance I get it out without it breaking. It's the second picture in the first post This whole setup is quite finicky and I've thought a few times about trying to engineer some kind of replacement, but not sure if the interest would justify it.

I will double check that but I don't believe any of that has been changed since my last test fire. I did remove the combo switches and reinstall. Maybe I messed something up there

@solly I don’t believe you answered my question about the check valve. Trying to offer known problems that cause what you are describing

Called a "reaction disc"

It's always a mistake to paint/powder coat those rear stub axle brake drum flanges, Nissan didn't.

Well you do! You have an excellent camera.
