Hi all, get really good answers to questions on this site, well here it is: My two front doors (1979 BJ 40) have really punky bottoms ,about 4" on the bottom that need to be replaced. I have seen replacement bottoms from Texas Cruisers? and they look pretty good? any suggestions on this product and the work required. I am no body man, but I'll take a wack at it if it's not too bad.. Help my doors are in need of some serious TLC.
