HELP! I have need of some stuff for my 46 burb. Since this is an all panel/burb forum I thought I would try again here

. My window glass tracks are not too great

. The ones for the 2 side windows on each side, not the door ones. Would love to replace a couple of them and NEED to replace 1.
Are there any other more readily availably tracks that would work or that I could weld 2 pieces together or something. I guess that's it for now. Will post picts as I get farther along.
thanks
jim
