If so, I think that if you fabricated your own floor tunnel to allow some extra room for the uncut tremec case you could get away with using a flat piece of steel for the rear crossmember hoop to maintain some strength and support for the floor tunnel. If you had an uncut tremec to trial fit I bet your floor can be modified fairly easy. The template I made for the floor might allow plenty of room without the top hoop of the rear crossmember for the uncut tremec. But, I have never seen what the uncut tremec looks like. Don't know if this helps any.
