Hi, looking for a bit of guidance / help here if possible. My best friend passed away and had a 65 fastback and I’m helping the family dispose of it. It’s been sitting for a number of years but had new floor pans installed, frame rails and quarters. It is a roller and believe all parts are there including folding rear seat etc. Was originally a 289 automatic and believe original block, trans etc are there as well. Windshield is broken, but rest of glass is there and intact.
Have no idea of the value of it, so am looking for some help with this.
Thanks in advance.
