I have heard of people swapping the outer wheel housings and stretching the quarters over them. I got new frame rails for christmas as well as about 4 new sets of jackstands. Yesterday I cut out the rear rails and all the trunk floor sheet metal and i will be putting the new rails in today (at least starting to anyways). I am replacing the outer housings and have modified the inners to do a minitub. I would like to do a flare on the quarters if possible. If anyone here has done this, let me know how, thanks.
