I have the weld in brackets and what are labeled as both front screw on brackets, but not the rears. Anybody have some of these?
Sorry I can help since I already sold the only set I have, but for anyone wondering, here is what the rear brackets look like: Here are a bunch more photos that show the center and front brackets on a set of labeled convertible 1/4 panels. Strangely the center bracket was welded in place on the driver side (between the wheelhouse and 1/4 panel skin) but on the passenger side the center bracket was bolted on. The front and rear brackets were screwed on with u-shaped speed nuts as shown.
I took those photos so that the guy buying the brackets would know which bracket goes in each location. The most surprising thing to me is that I actually saved the photos in a place where I was able to find them again.
