Thanks everyone. I really hoped it could be salvaged.

Maybe I can just forego the shim in that hole... LOL

The rim on the (short side), the plate that covers the internals, was pushed in to the point that it distorted the hole. About 2mm. Look closely at the 1st and third pic. The 1st one shows through the good hole, how far out of round it is. Do you think re-drilling it would be ok? I'm not trying to be an ass. It just makes me kind of nervous. It fell pretty hard.

Well, I finally got a chance to sit down and inspect my differential. It would appear that it was dropped from a considerable height I guess you get what you pay for. Now I have the dubious pleasure of returning it to Malaysia... grr

I am. '96 out of a Z28. LT4 cam and carbureted

I've considered removing hood height adjusters, putting pins in their place, and cutting rubber or urethane to slide over the pins to retain the proper alignment with the fender/ cowl.

I know this is an old thread but I'm new on here. Stock tire on the '78. (Which is what I have) is 195-70-R14 which yields 24.7" tire diameter. I currently have 225-60-R14 (24.6") 255-40-R17s are supposed to be 10.04" wide and 25" dia. I'm looking to keep speedo/odo numbers accurate. I'm also interested to know how you're reattaching outer and inner fender wells. I've never done much body work. If you have any advice to someone who's treading into new territory, I'd surely appreciate it!

Thank you, I'm on it. I'm going to have local shop that specializes in rear-ends and manual trans install it for me. It may be fine but it's nice to know where to get the parts if I need them!

Question about your extra clutch upgrade. My diff will be delivered on Monday and it was very inexpensive. I expect a fair amount of wear and every time I google the part I'm looking for, I get referred to places that sell new diffs. Not rebuild parts. Any advice?

According to my JTR manual, my 78 weighs 2750lbs. With the LT1 eng, Tremec TKO 3550 trans and Lakewood, steel bell housing, I added about 80lbs to the car. (Aluminum heads, intake and radiator). Pretty fair trade-off, since I added an additional 250 hp over the factory eng!

Yes I am!

I noticed most V8 Z cars don't have A/C. I plan to bring the car to an auto-air place to have the hoses made and complete the installation. I couldn't find any existing brackets for my alternator and A/C compressor, so I made my own. Any thoughts?

Thank you.

Maybe because I wasn't born with this information in my head.

I'd like to think that's true. Something about throwing 400 lb ft of torque at it makes me feel that it's got to shift. Especially with 10in wide tires. At 2 bucks a piece, I'll have more peace of mind. I promise you I've wasted $20 on worse!

I'm sure there are folks who have info like this already but I wanted to share something I found. lantech.com has sleeves that are 12mm od 10mm id and 10mm long. p/n 000457A I based that on an 11mm thick flange for mounting the ring gear. If the flange is thinner than that, p/n 000456A is the same as above but 8mm long.

No, not on this site. These are guys who race, that I know personally and professionally. I'm a mechanic but not an auto mechanic. I work on heavy equipment so we're inclined to go with the idea that, "if there's smoke there's fire." OBX may be getting a bad rap but, until they're proven, I don't want my car to be a test bed. The VLSD out of the Silva has been proven to take a beating and they're very affordable so that's the diff I chose!

Great! Thank you!

Tell me about your wheels and tires... They're exactly what I'm looking for!

Can anyone tell me if they've purchased a differential from JDM-Motorparts on ebay? They're shipping from Malaysia and I was wondering if I can get some feedback on their experience with them.

I looked at them but I heard too many stories about poor tooling and internal parts breaking. I have a close friend that races and some of his associates weren't satisfied. He keeps pushing the KAAZ SBN2655 but they chatter a bit too much for street use. I was almost sold on the Quaife but I found some shims that are perfect S13-S14 swap. I'm just about convinced to buy a JDM on ebay and refresh the clutches.

It'll probably be a month or so before I make a purchase. If I miss out on the Z31T, I'm sure another one will be available. I value all the input I've read so I can make an educated decision.

I greatly, appreciate this info. Thank you very much. I'm pretty sure I'm going with QDF7L. Spend it now, save it later!
