swap 8 3/4 rear end for 9 1/4 in 96 Ram 1500

I want to swap a late model D100 truck 8 3/4 rear end into my 96 Ram 1500.

My only concern is how to adapt the anti lock brakes to the older rear end.

Does anybody have any ideas on this?  

Thats the tough part as the 91/4 housing is machined for the speed sensor, and the tone wheel is pressed onto the differential carrier between the ring gear and the carrier, I would keep the 91/4 in anyway, they are good rears...  

now you say there a good rear. is there anything that needs to be done to them to make them stronger?  i hear alot of bad things about them. what is so bad about them?  what i am planning on doing is beefing one up basicly stock parts to be able to pull with in a mod small block truck class.  

I wouldn't do it. Generally, as ring gear diameter gets larger, so does the rear axle strength as a whole. I would work on the 9.25s shortcomings...if there are any.

well i have about a dozen of them that people keep giving to me because they say there "junk" but i have seen 9.25s put through alot of crap that it proly shouldnt have and still hold up.  is there anything i can do to prolong the life out of one.  its only a mod small block class that pulls a lite sled.  my girlfriend is the one that wants to run the truck.  i already have my own with a dana 60 in the front and a 70 in the rear.  but with the engine and trans that i build for her truck, it isnt going to be to stressful on the rest of the drive line.  just woundering if there was anything imperticular i can do to them.  

Listen, the issues with the 91/4 rear is 1) the anti-spin diff unit fails due to the retaining clips breaking and 2) bearing failure due to improper (excessive) preload. Use an aftermarket unit (detroitlocker, auburn,strange,etc.) and strongly recommend bracing the housing due to axle tube flex, so brace,brace, and again BRACE the housing, you know most rear failures (ring and pinion)damage is due to housing movement under load .  

ok so brace the heck out of it.  so is there any way of makeing the pinion bearings stronger by posably machining it to fit a larger bearing in its place or even a double roller bearing?  

I dont feel that is needed,the o.e.m. bearings are fine, just use the service manual specs for proper preload, it will live a long happy life.
By machining the housing you are taking metal away in the thrust area of the housing there by weakening the housing.  

ok cool thanks alot.
