I know this is an old thread but I have a quick question.
My son and I are trying to install a new headliner in his goon.
At the rear edge of the headliner there is a piece of cardboard that is sew into the rear edge. Is that hard edge to be slipped into the metal channel at the rear of the roof and then the headliner is folded back towards the front. If it's not locked into the slot it would have to be glued on top of the metal channel. The problem we have is if we lock the cardboard into the slot our headliner seems about an 1" short. The bows won't stand up verticall
