If it doesn't have a trim tag and your Dad wants to keep it original, I can decode the car for you without a trim tag, to build a new trim tag with. But if your dad is going to chop it up, then the trim tag won't be necessary.
It does have a fender tag and build sheet. Between he and I, we have a couple LA’s we can use. I’m going to talk him into a TKX or a modern o/d automatic.
He’ll need a rearend. I think I’ve got him convinced to do a 8.25. He said no to the 8.8 Ford.
He has several sets of E-body buckets we might try to use. He likes the bench too.
