Numbers matching isn't so important today, unless you were going for a bone stock resto with like a 69 yenko or some super rare model.I say it also depends on if the car is numbers matching, RS or SS, and the options the car came with.
If it is in decent shape and a numbers matching car you could invest 10-15K into a professional restoration and sell the thing for profit.
:hehe: I'm dying! I'm a big Rod and Camaro guy and I didn't even catch thatWay too many variables to decide without pics and documention. IMO 25k sounds kinda steep for that. (350/350) average restoration. BTW TH350 is a 3 speed. Not being a smarta**, just letting you know.
