I looked to do this same project several years ago. Some members gave me some great contacts of quality shops that would been able to pull this off. Prices were in the 25-30k range plus the price of a Z to chop. Some shops also gave me an hourly rate only. Most wanted to buy a donor C4 convert. and strip it down for all the parts needed.
If Brett can pull this off (which I'm sure he can I would be interested in also having it done) I might have a line on a perfect ZR-1 to CHOP! No, not my 95
Keep us updated
I forgot, the idea of making her a roadster with no top at all was also tossed around by some shops.
