Only one carrier for this rear.Nothing made anymore.No-Spin was GM`s name for it.It`s actually a Detroit Locker.Look on the passenger side between the seat and door on the back wall.there will be a vehicle jacking warning label if it was equipped with a locker,if it`s still there.A trick that can be done is get the full-floating 14-bolt Locker that is available.Due to finer spline,you`ll need the shafts from a 14-bolt that will need something like 3/4-1" cut off the ends.You`d want to do your own sizing on that.But,that`s the general idea.Used original units are around.I`ve gathered 3 in the last couple years.These rears are tough.Finding a donar 14-bolt will be easy since they replaced the HO-series in`73 and kept on going in anything 8-lug.
You could stay with 8-lug andwhen you swap to disc if you want.Spindles up into the 88-ups work.There`s a tie rod diference to convert.Discs for the rear are avilable or easy to make brackets.There`s a board sponsoring vendor called Blackbirds that offers a specific kit or 14-bolt kits can be made to work.
