Which ZR-1 Unique Parts are NLA from GM?

[93RubyZ]

As part of my research: http://www.zr1netregistry.com/forum/...ead.php?t=3159, I'm looking for more information on the ZR-1.

I need to compile a list of ZR-1 specific parts that are no longer available from GM. The entire LT-5 engine can be categorized as one item, no need to list all the individual parts

I'd like to get this information if you know it:

1. Part that is NLA
2. GM part number
3. Is there an aftermarket source for this part and who offers it?

When I'm done, hopefully all the information will actually be useful to ZR-1 owners or prospective owners.

Thanks!
