I just received this car and from what I know it numbers matching in bad shape as it has been sitting for a number of years in my dads back yard, My real issue is what is worth doing to this car, keepin it original or just make the custom ride happen, if I go the custom way how do I get parts for the 455 engine and what parts are interchangeable. for instance I know that the regals montes, and grand prix of the 80's share many parts, is there a car that could be a donor thats not a riv. thanks for any help, this is new to me, the car is older than me and I have not much experience in this group.
