42RH / A-500 in a Duster with pictures.

Thanks. By crossmember I was refering to the Chassis component not the trans support(lower) crossmember. When you added the 1/4" support over the tranny how much clearance was left between it and the trans? I'm hoping to do the reinforcement inside through the floor. It will protrude up about 3/4". See the pics in my thread about the size and location. My use of a lift is very limited and I would like to do as much on the ground as possible before "borrowing" a lift. I know most of the original structure will have to go. Just interested in how much can remain and still have reasonable clearance.
Thanks again.
