I believe 1981 was the last year you could get a 14 bolt full floater in a Suburban. All 3/4 ton Suburbans got a 14 bolt, 8 lug rear. From 1973-198x it was the 14bff. From 198x-1991 it was the less desirable 14bsf.
No Suburban ever had a front Dana 60 from the factory. Whether a 1/2 or 3/4 ton Suburban, all 4x4's from 1973-197x (I've seen some 1980's with a Dana 44) had Dana 44 front axles, and from 197x-1991 they all had 10 bolt front axles.
