I have a 1938 chevy sedan and want to get rid of the vent window (quarter glass window) in the front doors. I have found a conversion kit online to do it. Has anyone actually done this and would have any pros or cons tips on doing it?

Hey guys, just planning out the next steps on my build. I have a '38 Chevy half ton, which has the same frame as the '37's. Im just a bit worried as to how much HP/TQ I can put under the hood, but Im quite leery, as the frame is only 1/8" thick steel, thats formed into a 4" steel C channel...
