PST's Project Duster

Well progress has been slow, I have been finishing up a few other projects. I did get back in the trunk this past weekend. This Duster definitely has had some rear end damage in it's lifetime and just by the way that the mount/brace for the trunk latch was booger welded on the repairs were not up to my standards.

What I am not happy with is the fit of the repair panel. I understand that aftermarket panel never fit perfect. But I think one of the frame rails maybe be tweaked.

Does anyone have the factory measurement on the frame rails of a 72 Duster? I would like to double so if there is a problem I can tow it over to a friends shop to use his frame straightener to correct the issue before installing the trunk floor.

Thanks in advance.
