Re: How should I weld the \'73 window frame on my \'89 K5?
Before I cut the old frame I measured in three or four spots to survey the opening size. I started about 12" in from the side, then measured every foot or so (top to bottm dimension was 23.5") i measured without the glass is the frame (kinda obvious /forums/images/graemlins/blush.gif) and without the window rubber either. I made sure to measure where the edges were good, cuz in some places it was a bit rusty/scaly.
The pins being a snug fit helped keep the winshield frame at the correct angle. Once it was sitting there on the pins I just verified I had the same 23.5" in the same places and tacked it up.
Seems harder than it really was. In fact the cutting of the old frame and new frame was the hardest part IMO. I used a stretchy string line from post to post. I made sure it was dead straight by measuring from the edge of the string line to the edge of the frame and then marked it. I tried to keep my cuts 90 degrees to the side posts on both. I did still have a slight gap though, but it helped more than it hurt.
