Thanks for the information on the frames. My GS frame is much rustier than I expected. Anybody have a photo of the triangle piece on the GS frame or other differences between the GS and skylark convertible frame? My GS frame didn't have any triangle piece although it is boxed and has the 4spd components. My skylark frame also is boxed and reinforced in the rear but the reinforcement is a long rectangular piece not a triangle piece on a cross memeber To be honest, other than the 4 spd components, The frames look alike. That may be due to the fact that the GS frame is pretty rough and even has been patched up on the driver's side all the way down the outside edge.
I am going to use the skylark frame as my base but my GS frame doesn't provide much of a guide for any differences. Any more details on the differences between a skylark convert frame and a GS frame from anyone would really be appreciated. I would like to make the skylark frame correct for my car. I have tried all sorts of google searches looking for photos of GS frames and have come up empty.
As always, Thanks Rob K
