While it's not what you specified, I have a C&C DRW D-70, 35-spline out of my 90 with a tight and well working Powr-Lok as another option to consider. Application dependent, though. What are your plans for the truck?
My first gen is a fleet side dually with the wide 70. The rear has some issues along with the bed. I was planning a bed swap similar to a step side so it could be narrowed up a bit. Its a daily driver that does tow duties. I've got a transmission swap in mind also. I could settle for a drum 80 if the price is right.
I'll let go of either of mine for $450.
If you're along I-70 in Missouri, Southern Illinois, Southern Indiana, or around Columbus, Ohio, I can probably deliver next week.
