I know I asked this question before. I got a 54 Chevy with the vent windows and I want to put one piece glass in. I know in certain year Chevys have one piece glass but the door handles push down. I have access to this particular door and I took some pictures and to me it is very similar to my 54 doors. The window trim is a little bit different. What would it take to put OPG into my doors? I would like to crank them up instead of using a power window kit. I know it has been done before and I’m not sure what it would take to do the conversion.
