If i already had the alterkation i would've started doing this already, but for now i have the torsion bars still in place(saving for alterkation now). Which is why i'm fielding some opinions on the subject. Because even with torsion bars i would think that the sub-frames would stiffen up that area so that it wouldnt flex.
And that it may only come in to play(big *may*) if one were to remove the center crossmember with the torsion bars loaded.
But what do i know, i'm just joe blow trying to work around a design that never intended to have large overdrive transmissions.
