GMC people i need drive shaft help!!!

[ol yellow 72]

i got a 72 GMC and ive had couriour bearing issues. so when i dropped the drive shaft the center bearing support ( the bracket where the couriour bearing bolts to) is broken, its been welded in the past. so i go to the local salvage yard to get the piece and out of the 12 67-72 there is no GMCs so i looked the chevys over and seen its different the chevy has a strait 2 bolt bearing and my GMCs is horse shoe shaped, so if i can find one for a GMC, then imm gonna have to get a chevy one and weld it in, so will i have to change the drive shaft too?
please help i wanna drive my baby again.
