raising the "hoop" in trailing arm crossmember?

[statenine]

Hey guys, does anyone know the best way to raise the hoop in the trailing arm crossmember (with cab still on)? I have a 1 piece driveshaft and and I am bagging the rear with an 8" notch, and was told I will definitely need to cut and raise the hoop about 3" in the TA crossmember for clearance. Should I just cut out the top portion of the hoop and add some kind of spacer in to make it higher? Or use a custom U shaped piece of metal to replace what I cut out? Thx in advance!
