I added about a 1/2" of spacers at the top and bottom to make the track tighter to the window. I could run the window up and down without bolting the window tabs and it stayed level.
widening the front rail and moving it forward is still important, it is still tight at the top. I think grinding about 3/16" off the front edge of the glass would be better but I'm not about to try that.
Happy to have my window back. THANKS, to ALL for these fixes.
