Yes, hold my beer and watch this! Coming as soon as possible after I swap the radiator from my old Jeep.
Gain #1 comes from having a single sheet of steel. 6mm is the most I can get bent locally, with some extra metal welded on the sides it should be good. Plus if I use studs instead of bolts for attaching the trans mount to the crossmember I don't need extra thickness for nuts. Some 10mm wheel studs should be easy to find.
Gain #2 comes from lifting the entire transmission up. Still thinking if I should clock the transfer case or not.
