Hello all. I am looking a a ‘74 rig with a low mile Chevy 350ci v8 conversion. It’s in beautiful, mostly original shape otherwise. It’’s 99% rust free but does have diamond plate on the rear sides. Looking at what’s behind the diamond, there is very little rust damage being covered up. Does the diamond plating and V8 conversion diminish the value of this vehicle? Trying to determine if it’s priced appropriately.
