StreetStangs.net - View Single Post - Weld torque boxes before installing LCAs?

I acquired a set of MMR ( http://www.modularmustangracing.com ) LCAs with poly sphereical bushings, they supposedly come from the same manufacturer as Granatelli's.

I've read that the increased load from the poly bushings can cause lots of bind and stress on the torque boxes, should I have the torque boxes welded up prior to installing the LCAs? Or install them and then do it, or not bother with it at all? I'll probably go ahead and get my axle tubes done and have my subframe welds touched up while I'm at it (got a few creeks in the backseat floorboard when I walk across it).

My car's auto and won't see a high stall converter for a while yet probably, the stock stall only hits 1.9 60's on drag radials and spray.
