Curious if anyone here has custom built steel glass channels for their car doors? On my 31 tudor I've thought about making quarter glass solid and rear window roll up and down. If I follow that thought I figured to build a nice glass steel channel to actually follow around the top and sides of the rear glass opening and tack weld into place with a 60's-70's style rubber track to slide into the channel for the glass to slide in. In fact if I can get a good plan of attack I may do it to the quarter windows instead. So I'm thinking a thin steel u channel that I can some how roll curves in and fit to glass openings but looking for any ideas ! Anyone know of a good place to buy steel channel from? Thanks guys any insight would be appreciated !
