XJ dana 35 to 8.25c swap

[mtbxj87]

Im done withe d35 in my '89 xj auto np231. The 8.25 is on its way to me. From what ive found my driveshaft should work. Obviously the u bolts and spring plates wont work. My question is: Will the brakes work or can i use the brakes off the 35? (drums, they are less than 5000 miles used on the 35).
Thanks!

All depends on what the 8.25 is off of. If it came from an XJ, should be a direct bolt up but depending on year of the axle, your drums might not work. 96+ had larger drums on them.

Throw on some ZJ discs before while the 8.25 is on jack stands. Then just get plates and u-bolts and bolt it up and bleed the brakes.

I got the 8.25 in. Everything went great. I turns out I did have the bigger 10inch drums on my Dana 35. I didn't use them cause the axle tube is .25" larger then the 35 and the backing plate bolt holes are too far off. So I turned the drums that came on the new axle and used the brakes off it. My old ebrake cables worked but the housings are almost too short. I did bend up some new hard brake lines.
I still have a awful grinding noise coming from the np231 that is throwing me for a loop.
