Evac> Your best bet is to find a Ford or Dodge van rearend. I believe a 73 on up GM 14 bolt will work also. They'll be a little, wider but they should work. You'll have to do some fabricating by cutting off the old and welding on new spring and shock mounts. If you want to upgrade your brakes on all 4 corners, try finding a 1/2 ton front axle assembly and a later model 6 lug rearend.
