I have a 1991 turbo Legacy with a bad transmission and I'm getting parts for a WRX transmission swap.
Right now I have:
a complete 2003 WRX transmission assembly
rear diff
rear axles
wrx flywheel
wrx clutch
wrx pressure plate & tob
I want to be able to swap out full WRX rear axles if needed
in the future so to do this do I need the hubs,
will I need anything other than hubs to match the knuckles.
Would there be any issues with me n me keeping the 91 legacy parking brake assembly, knuckles,rotors,, etc and just adding the hubs to what I have for the swap?
Also is there any difference between the stock 1991 LSD unit and a 2003
LSD unit?
I am aware of ratio difference for teh whole differential , but I
am focused on the LSD or VLSD units themselves.
WRX trany swap: do I need rear hubs or hubs and knuckles?

No, the VLSD's should be the same.

You don't need to replace anything to get the WRX driveline to bolt up. WRX axles will fit in place of the Legacy axles just fine. No hub/knuckle swaps required.
You have all the parts you'd need to do the swap now. The only thing you'll need to change is the pinion flange on the rear diff if you plan to reuse the Legacy driveshaft. The bolt spacing is a bit different between new and old styles. No big deal to swap though.

i also have a bad trans in the 91 and would like a trans that would hold a bit more power. i have been thinking about doing some kind of wrx tranny swap but i don't know what to get. do i just need a wrx tranny, the clutch and flywheel kit, and the pinion flange off the wrx rear diff, to just bolt on?
