After removing the sliders and finding out how bad they are rotted on the bottoms, I have decided to rebuild them, I have an extra set from another 57 Suburban and hopefully I can use both sets to make one good set. I carefully removed the glass, documenting the order in which the rubbers and trims all go very carefully, I dropped all the glass off to my friends glass shop, They are looking for the right thickness glass in the same tinted grey color that will match the one pc. power windows I have for the doors, that I bought 10 years ago. I do not have the rear glass, I am changing the rear hatch to barn doors and I am missing the glass to those doors, I will have to make a template out of 1/4 inch plywood and drop that to the glass shop as well. Not sure if I have the rubbers for them, Will have to check my box of parts. I have decided to keep the original motor 347 pontiac with the hydromatic transmission, I will have to figure out brackets to work with the AC unit that will be installed. But figure that should be easier and much less expensive than changing the motor and transmission to a chevy motor. (hopefully). I have the parts ready to go to the chrome shop, maybe this week if I have a chance to drive there. Hopefully, I can do some more welding on it tomorrow, expecting some fender tips this week and have a couple more small patches to make around the wheel wells. And have to weld in the new steps which I already have cut out and fitted. Trying not to forget anything that will make me have to take apart things I have already done.
