My newly purchased 69 convertible needs window adjustmemt/alignment. Windows roll up and down with difficulty. Side windows don't always align properly with smaller rear seat windows and rag top. Rubber and felt are new. Door panel fit is decent. Before I take it to a body shop, I want to know is this a difficult fix or just adjustments needed? Also, would you recommend installing some kind of X brace to the frame to keep it from sagging or twisting in the future?
