It's only a problem if you don't know about it and find out the hard way. (thanks)

They make kits for the torque boxes (waaaaay over priced IMO, $250 upper & lower for $20 worth of sheet metal and bolts). If you know a welder you could have them fully weld all the seams within about 6" of the boxes inside & out (rally racers do this to the entire car, almost eliminates the need for a cage!!!) and box them in (weld a plate across the bottom of the torque boxes). If they can, have them fab pieces like the battle boxes and weld them in also.

Weld ing the seams is a good idea even if you have the battle boxes.

Pinion angle is easy to check but I don't know if you can change it with the stock control arms (w/adj uppers it's easy also). If you don't have one go to Sears and buy a universal protractor (angle finder) probably about $20. Remove the drive shaft and place the angle finder on the pinion flange, read angle.

An artical in 5.0 mag. about reducing 60' times one of the drivers says for a street/strip car PA should be 3* (front of diff angled down I think).
