I came across an attic full of classic Cadillac parts from the cars my father used to own. They have been up there for 30+ years. Most are N.O.S. parts, my father was a purist, and originality was paramount to him. Back to my point. I need assistance with their worth/pricing. I have done some research into it, but there is alot of s@#$ up there....any help appreciated, thanks.
