Junkyard swaps: Rear brake options for 8 1/4 and 8 3/4 axles.

Looking at the Rock Auto website, the early Cherokees did use 9" drums with a Dana 35 axle.
Couple observations.

In the past when i had abundant time, i would do anything to save a buck, but spending $120 on drum brakes you have to pull yourself seems pretty steep, especially rusty ones that need half the stuff replaced.

You can piece together a disc setup via rockauto for under $200. Easy. Hell Speedway sells one for $350 complete for a 8 3/4.

If you do want to keep drums. I have some 10 inch ones and some 11 inch ones for a 8.75.

Also have whatever comes on a running, driving 1977 8.25. Would let them go for a song if needed. Lmk.
