bummer Dave, looks like this will be a hard "wish item" to find, maybe if the 79's are unavailable we could find a complete set of 80's? his car is after all an 80 and the 79s are not the right ones, just thought it might be easier to find the one vs a set of 4.
I sent him an 80 passenger front, haven't pulled the driver side but know it looks good, mounting is the only worry. I know I don't have any good rears, up here in rust country they are one of the first things to rust away. I already have one "glued" on because the mounts are gone.
