2 piece driveshaft angle adjustment????

[Hottrucks]

ok heres the issue has anyone shim there carrier down to change the angle of the DS....when I get low I can feel the shaft come into a vibration so my thought was to drop the carrier a bit buy taking out the bolt and putting something under it and using longer bolts??? havn't really looke at it kinda going by memory??

or an other ideas?? one piece isnt really an option? but??? if there is a bone yard replacement I may try it ( need year and info if they are available)

thanx
