McQuire Chevy dealership here in Clare, MI does some fine work. They have done a few 65-67 GTO's for the owner of the dealership. They also did a mostly stock resto on a 70 nova ss for $22K. That included engine, trans, interior, etc. I was told that my 68 convert bird would be around $5K without seeing the car! But I can't swing that kind of cash right know.
My son will finish my bird before I do,(he's 3 yr's old)!!
