I'm going to make mine so it mounts to the subframe connectors also. I think I'm gonna use 1/4" thick flat bar to tie the top of the old torsion bar cross member back together, so the trans tunnel doesn't end up so big. I'm just going to use the 2 holes, and not worry about the one towards the rear. A 545RFE makes an 833 seem like picking up a paper clip! lol
