1974 Scamp #2

Working on the passenger side door lately. Got the door latch and handles all in and working. I didn't take them apart and the PO didn't label left or right on the parts. I put the door seal on last night. New seals came with the car. As did all the rubber parts. Wasn't happy with the quality of the door seal. No metal backer like the stock one. So I stripped the old rubber off the old metal backer and glued it to the back or the new seal. Just have window left to put in. Thinking about tint. Not sure if it would be best to tint before or after I install the windows in the doors.
