i think you can move your existing crossmember 3" forward, but I think you'll need a th400 yoke on your driveshaft............ and your driveshaft will need to be lengthened approx 3"

Thank you very much, i going to buy a new driveshaft. That sounds easy enough to do.

Also if you can find one get a 75 or older X-member as they have room for dual exhuast or 3/4 ton with some minor fab work room for 3" dual exhaus.Like this
