The sulfur question is more complicated than just GL-4 versus GL-5. There are GL-5 rated lubes out there that work fine with "yellow-metal" synchros. The GL spec. is a performance specification, and doesn't tell anything about how the formulator made the lube hit the spec. number. It's a pretty interesting area if you're in to that kind of thing. But, overall, it's most effective to just go with what has worked for other people. Redline has a great reputation.

Okay, I'll rephrase. If I can take some measurements for you let me know. I have the OE '72 radiator hanging on a nail in my garage. I've installed the larger 280 radiator in my 240. Fits great although it's 2" lower to the ground but still not as low as my front spoiler.

That's a good question. I think that the ZX module's have current-limiting technology like the HEI modules, which should work with any coil of higher resistance than stock. But I can't find any documentation, and the ZX coils are 0.84 - 1.02 ohms, higher than the HEI's ~0.5 - 0.7 ohms, and higher than the early 280Z's ~ 0.5 ohms. . You might measure yours, since aftermarket parts tend to vary. If you're around 1 ohm, you're probably fine. Note also that the manufacturer's spec their parts to last 10's of thousands of miles. If your coil's not getting hot it's probably not a problem. It's the heat over time that bakes them.

This an old scool frame rack. It gives you an idea of what is involved. Casey

Forgive me guys if I'm incorrect, but I think there might be some confusion about what is being asked for here... Rolf, You're looking for a dimensioned mechanical drawing (a "blueprint") for the radiator, right? If that's the case, I don't have what you're looking for, but it might help others understand what it is you are asking about.

I've read of erratic timing with one of the odd modules, -92 or -93. Fixed by adding a power line to it. Just saying, somehow,there's a way to have a problem, if it's not the E12-80. But you can change them with the distributor installed so not a big deal if you start with one, then switch. Found one thread (nasty people...). classiczcars even got a reference for a picture. http://community.ratsun.net/topic/56630-e12-92-retard-or-no-retard/

You found the problem. It is the ignition unit. Here is how to upgrade as you rightly suggest. Www.Atlanticz.ca/zclub/techtips/distributor
