All I can say is the X-member needs to go back about 2 inches, and I would imagine the drive shaft needs hacked too.

The hot rod;
a'69 G.M.C. Short/Fleet. 350 W/a heluva cam and nice stance. Trying to clean up the left over damage from the Dope-Smokin-Old-Man. See it at http://geocities.com/andys_69_gmc/

I've been dubbed the Longhorn Freak/Fanatic/Expert, I just hope I can live up to it. Check out my Longhorn site at http://geocities.com/MotorCity/Flats/8752/

Need to pick up the one ton Longhorn with a PONTIAC 350/350 here soon, thanks every one!
