I found a very nice 65 truck partially redone and looks good and need to sell only problem is its BBW and I just hate the look has anyone took a BBW cab and make it back to the small window? I hate to pass up this opportunity on a repaired cab and all of the cabs i find around here the brow or the inside of the cab is rusted thru and need fixed this one has been repaired and painted with new rockers cab corners front fenders not sure what to do thinkin bout buying to see if it grows on me
