I was under my brother-in-laws Trans Am (99) changing the rear fluid, and
lemme tell ya,,, if you want some ideas on how to strengthen up some crap,
look under one of these babys... Standard Real Traction Bars (From axle, to
frame) What appeared to be something to keep the transmission and rear rock
solid (big long metal thing goin from tranny to rear) 2 bars in a sideways V
shape from the rear tires.... There is wayyyy to much crap on the T/A... If
you are lookin for strength, or what ever on anything... get under one...
you will be quite amazed =-)
