The roll bar is 3/4 of an inch too narrow... tried unsucessfully for 20 minutes to stretch it. bzzzt. try again.,,, I installed it on the right side, then muscled it into place on the left side, and drilled, deburred and reamed one hole at a time... fits like a glove. After the roll bar was done, I clecoed and drilled and deburred the panel, trial fit, then cs'd everything installed the nutplates and assembled
