Big dumb and happy here , I'm going to install new quarters on my RS/SS Big block. I've taken it off the rotisserie and supported it at the front subframe ,and the rear axle mounts. (6 location) I'm going to rebuild the hinges on my doors. I have a box tubing cage installed to keep the body from warping while I installed the roof structure , floor,etc. I'll cut that out and install the doors and get them to fit the existing quarters with good tolerances . Then remove the existing quarters and install the new one to fit the doors ,trunk gutter , sail panel. 80 hrs later I'm done. Please let me if my process has any flaws or if you have tips on ? Thanks in advance , build on!
