I hope you can do the work including body and paint or you’ll be into it more than it’s worth. Different animal than a Nova. Lots of basic chevy parts including new sheet metal for the nova, not so for the Jetfire.
Completely different car than a 65 442 which is basically a GM “A” body which you can practically build out of a catalog. Different running gear, suspension, eng, trans, body, interior, electrical, etc than the A body or early Nova.
Great car but a different animal. Oh, and you need a rebuilt turbo for the Jetfire along with the ancillary parts. Rebuild for an existing turbo is around $3500 or so, is that about right Jim?
