1991 ZR-1 Exhaust Manifold Bolt Specs

[hottrodcrazy]

I need replacement exhaust manifold bolts for my '91 ZR-1 and the dealership here can't track any down and I'm not finding them online anywhere. Can someone provide me with the specs or tell me where I can find the specs so that I can try to replace them with another bolt that would match?

Or if anyone knows where I can find the bolts that would be great also. Thanks.

The stock bolts have a sintered metal sleeve/spacer that was held onto the bolt with a retaining clip. We do not have the spacers, but they can be made easily fron 1/4" schedule 40 black or galvanized pipe which is readily available at any hardware store.

Thanks for that info. I'll look into that. The bolts for the ZR1 are going to be different from standard c4 exhaust manifold bolts I imagine right? I can find those with no problem so I just want to make sure they aren't the same bolts.
