yes, they are all 8" diffs as long as one wasn't a 2wd (which has a 7.5")

No problem.
I'm still doing the research on the 4Runner(?). So far, it looks like I need to change that to atleast 84-09(maybe 84-present?) 4Runner rear axles. I'll fix that. I just find it hard to believe that they still use the same V6/Turbo 4cyl. diff for V8 4Runners. But I guess they do.
Of course they aren't identical to the the pre-96 diffs(but they're the same on the inside, and compatible swap wise AFAIK).

'96-up 4runner V6 diffs:
- new improved housing that looks the same as the T100/Tundra/Tacoma diff on the outside, internals are all the same as the regular V6 diff
- 30 spline pinion on OEM gears, swap pinion flange to 27 spline to use aftermarket gears

Are you saying that a rear 8" diff is a direct replacement for a 85 front axle.
I'm asking as ima do a SAS soon and thought I'd have to swap out r&p to match my rear 4.88 however I have another rear 4.88 8" as a spare

The only 8" rear that isn't a direct bolt on is the elocker diffs, but even those can be made to fit, somewhat easily.

The T100/Tundra/Tacoma diff
All 2wd and 4wd T100's, '00-06 Tundra's, and ?? Sequoia's use a newer/stronger 8" 2-pinion diff. Tacoma 4x4's and Tacoma PreRunner's that don't come with the electric locker (aka "non-TRD), as well as V6 Tacoma 4x2's also came with this diff.
This diff commonly and mistakenly called an 8.4" or 8.25" diff, possibly to imply its extra strength. The ring gear actually measures 8". The extra strength of this diff comes from the bearing cap/truss and large diameter pinion gear shaft.
LSD's available is the TRD/Kazuma clutch-type 3-pinion LSD, the OEM 4-pinion Tundra TRD LSD, and the Detroit Trutrac.
Lockers available are the Powertrax "Lock-right," "No-Slip," ARB Air Locker, Detroit Softlocker.
This diff cannot be fitted to an older style 8" axle because it uses a larger diameter mounting bolt pattern and because more space inside the housing necessary to accommodate the large bearing cap. The different bolt pattern also makes it very impractical to swap in an electric locking Toyota diff (the whole mounting flange would have to be re-done using a special jig).
- Carrier bearing truss and newer housing adds significant strength over V6 and 4cyl diffs
- Uses V6 carrier bearings, larger pinion bearings
- Uses shims for backlash adjustment instead of threaded adjusters
- Twelve 12mm Ring gear bolts
- 10mm axle housing studs with 14mm nuts
- 30 splilne axles
- 30 spline pinion
* 4Runners do NOT use this diff at all. Late-model 4Runners still use the V6 8" diff above.
