Help convince me to go BB in my Duster?

Expire said

So far I definitely will need disc brakes, a rearend and driveshaft, and was going to do torsion bars regardless. Do I need to modify the K-member?

I drove mine for over a decade with drums. The rear can be an 8.75 or a dana. You definitely don't need to run bigger bars. I ran .870 bars for the life of the suspension. Now I have an RMS and rocket here is running my bars and suspension. The Kmember will need a slight cut of its a 67-72 style. Not sure what mods are needed for spool mounts but I know the swap is still a bolt in deal.
