2wd could be special ordered with the 8.5" from '94- on, but only '98+ would have discs IIRC. They were also used in S10 Extreme's and would be std 2wd width
I wondered if the S10 Extreme's had the 8.5" as well, but werent listed as such in my GM info, or in any part# callouts.
Did all 4.3 with manual transmissions have that shock that mounted longitudinally? Its like a 3rd shock, but doesnt manage any vehicle weight, I think its there to stop wheelhop maybe.
I have no idea why GM wouldnt put the 8.5" rear in ALL of their F-bodies? That would have helped greatly.
