You mean around the back of the body? I left that factory lip for now. I am going to have a buddy do upholstery for me on the body and I want to see what he prefers before I get rid of the lip. I think rolling the interior fabric over that lip sort of like stock may work. Honestly haven't given it much thought yet. I was busy picking up raw materials and putting a lift up this past weekend so I didn't get any work done on the T. I'll be back on it this week. Engine comes out this weekend to go to the machine shop.
