it does when you get the SAS kit, most are made for 4x4 frames but they do have 2wd specific ones, not sure if there's any difference or not.

you doing a SAS, let me ask some questions, what gauges does it have for speedo and does or did it work? I ask because the 88 uses a vss or electric speedo, and the older t-cases use cable or what not. The newer cases with vss also have DS drop axles, not ps like the older gm's.

If you want the speedo to work it costs money for adapters or you can use a mech gauge or what not. The 88-91 burb and blazers have a PS drop np241 that has the vss and would work perfectly, or you can use what you got, but using a PS drop t-case requires trans crossmember custom built or fab work to an old one and alot of it.
