i was at the local pick and pull and found a 1993 montero sr
so i pulled the rear axle including the Ebrake and disk brakes along with the air pump to lock the rear diff.
the gear ratio is different from my raider. should i pull the front axle or just the 3rd member? Is the 2nd gen montero front axle stronger? also since the rear axle has disk brakes should i pull the brake master cyclinder and proportioning valve?

I put a 96 sr rear with disk brakes on my 88 SWB and did not replace MC. Brakes work perfectly!

Get the front upper control arms, spindles, brake calipers, cv axle, idler arm, and the front diff. That will be a good upgrade for your 88.

that 93 is gonna have the same diff as your 4cyl unless its a manual so your not gonna get a upgrade there and its also a vacuum actuated diff which is kinda a down grade compared to your 88 diff. if you want a good upgrade look at the diffs out of manual tranny 89-91 v6 models or 02-04 AWD montero sports but beware the sport diffs have a lower ratio in them so you'll need to swap out the rear r&p to match.

No they wont. The Gen 2 front diff is of high pinion design so the ring and pinion wont swap over. 4.625 is more than close enough. Run it as is you wont have any problems thats what I run in both my gen 1's without issue.

That rear end swap is going to make you very happy, especially if you have big tires. 35's was scary with the stock drum brakes. Make sure you have the driveshaft, mine had a larger joint on the axle, made me get a driveshaft. Definitely worth it though.

yes i have 35's that I cant wait to put on. So I need to get the complete drive shaft from the SR? is it the same length just with bigger joints front and back? Can i just remove the joints and install them on my raider drive shaft?

If your SR donor vehicle was a 95 1/2 or later you need the yoke off the flange side of the SR drive shaft and mate that to your 89 drive shaft..If you got the earlier rear end with the big pinion flange you need to get a custom drive shaft made..or swap pinion flanges on the diff...There's a thread here that covers this swap in a whole bunch of detail..
