need help notching cross members

alright i have a 78 c-10 long bed bagged in the back with a 2 link my problem is i hooked up my drive shaft and it hits the cross members i already notched one of them but i cant lay it out because it hits the cross member that the back cab body mounts sit on the problem with notching that cross member is that theres very little room between the cross member and my cab wall just wonder whats the best way to make room for my drive shaft

notch your cab with some 16 gauge steel, i had to do that with my sdime, and my yota. damn one peice drive shafts

no doubt they suck man i didnt want to do that much work just for the driveshaft but i guess if thats my only option its gonna have to be done

yea, it gets old not goin as low as you can, and hearing the rubbing sound, have fun, lol
