Needing some crossmember advice
 
Bought a 67 Step and it is lowered, don't know how far but I am ASSuming around 5-6 in the rear. My question is what does the pinion angle need to be now. Also my stock crossmember has grooved my driveshaft. Do I need to purchase the drop crossmember or change the pinion angle. All opinions are appreciated. Also the headers are the right part # but they are touching the A arm pivot point. Any suggestions? Thanx.

So, is this a dumb question or nobody wants to help? New to these trucks and was looking for some guidance.

I think it's a good question. I just dont know a good answer outside of groves in drive shaft ='s bad and dont pinion angles mess up the inside of your tranny with the extra strain. I say fab your cross member a little and reinforce it. You know like put a kind of c notch in it. :gi: maybe? Peace
