Gents,
I have an 89 f350 that has a industrial 5.9 12 valve with a eaton fuller 15 speed tranny. The truck has the original sterling 10.25 rearend with dually adapters. What I'm wondering is can I put 8 to 10 lug adapters on the dually adapters? Has anyone done this? Thanks

 

Its probably not the best idea to have adapters on the load-carrying end of the truck... nevermind piggy-backing adapters.

IMO, find at least a stock dually diff thats suitably wide so the bearing loads are somewhere close to the center of the wheels.
