Yep it's a long shot but hey, it's worth a chance right?
All seeks are for our 91 ZR-1 autocross car: Used and usable preferred, cheap helps!

Body/Trim:
horn button, left side (grey, if they're not all same)
triangular plug in console at driver's side seat control
front brake duct pieces

Driveline:
3.54 gear, low mile used (ie cheap take-out from a regular d44 car)
Tru-Trac or Torsen diff (a guy can dream, right?)
Aluminum flywheel, associated hardware

Suspension:
1000-1200 lb front leaf spring
tubular front sway bar
j55 hat front rotors (dreaming again)
front ABS sensors from an 88, big plus if the pigtail is available too
offset front control arm bushings

Engine:
underdrive pullies wp & alt
one bolt for steering cooler (somebody ate one of ours)

What the heck, worth a try. Sooner or later I'll find a couple of these on that "other" forum but hoped maybe some of the Z-specific stuff might be lurking here.

Best,

I have a set of stock rotors that where freshly milled before I got them. Not sure how much they're worth and they would be heavy to ship. Might take me a day or two to get them off. PM me if interested.

You can see the slight surface rust starting in this picture:

I've got the OEM set of rear end gears out of my 94. Haibeck did the swap to 4:10's. The gears have 17K miles on them. If interested, make me an offer I can't refuse.
also, like scholtmj, I've got a full set of front and rear rotors (never turned) with 17K on them off my 94.

Thanks for the responses. Agree the stock front rotors are heavy (20 freaking lbs each!) which is a good thing for track use, but for a nose heavy auto-x car I'm hoping to find some weight savings. The two-piece "hat" style is the approach, with an aluminum center "hat" and an iron ring. Problem is while it looks like they'd be reasonable at Coleman Racing, nobody has a ready recipe for which hat and ring. Maybe I'd do best to send them a stocker and see if they can match it. So thinking about that, a crap-tastic one near MI would be a great thing...

As for gears, the stock ZR-1 gear is 3.45. There was a 3.54 used somewhere in a C4, which makes it an okay swap in my rules setup (update/backdate among all c4's). It's not much of a change but any advantage is an advantage nonetheless, and the 'big guys' are all using them. It'd be more effective with the cammer though!

Last night I suddenly realized that my Bronco has a 3.54 D44 in front.... Hmmmm...... There's only 170k on that set!!

Some very early ZR1's had 3:54 gears in them.

There's been trouble documenting actual 3.54s in a ZR-1, that ratio shows up as used in '89 but very tough to confirm as I believe those were only prototypes. For my class it had to be offered to the public.

Option code GH0 shows 3.54 ratio but I am suddenly worried as I am googling it shows up in d36, and I don't really want to backdate all the way to that, although it might be lighter... I had thought maybe the 3.54 was the gear for an LT4?

Best,

Early production ZR1's had 3:54's in them as per a conversation with Gordon Killebrew.

I can tell you that 90 #354 had 3:45 gears
