window frame advice needed.

Just the rvt gasket sealer?
Yeah. 4 1/4 20 stainless steel bolts , 8 SS washers, 4 SS lock nuts all to mount the bracket. Rtv on the Bolt (hole itself) bolted it down and put some around the bolt head and washer, called it good. Never had a problem.

I'm actually working on a mounting stuff to the back of the truck now (because of what it is). If you want I can take a picture of the bracket and how its mounted.
