I tried to put my engine and transmission in yesterday and the transmission wouldn't go through the opening from the rear engine crossmember and the bottom of the cab. Do I have to remove this crossmember? If so, should I remove the rivets (its also the same ones that hold the brackets for the cab mounts), or should I cut it on each side flush with the frame rails? Will it need more structural bracing? I have the Mustang II crossmember up front so that helps some.
