In a '68, is it easier to assemble the quarter regulators and glass before or after bolting in the top frame? There is not much room in that area and I would like to make it as painless as possible. I can't remember the order when I took both of them completely out, two years ago. (I should have taken more pictures!)
The best way is to put the regulator in but do not bolt it . then slid the glass down and get the rollers lined up. then the hole thing will slide into place .
