The "Joe Parts" answer is that the inner wheelhouses are the same on the 68-72, but I can't find them anywhere separate, only as the 70-72 whole assembly. I'm seriously considering buying the whole units, and a pair of 69 outers, then mating the outer area of the 69 to the 70-72 units. First though, has anyone tried this, and are the inners available spearately? I'll be using the full trunk pan, and a full floor with rockers that I cut out of a car 20 years ago and stored in a barn, so it's going to be work either way.

I have never seen them separately. Your best bet would be to call one of the vendors and see what they can do. They just came out with the assemblies a few years ago, around the time the repo bodies came out.
