I went with https://forums.off-road.com/suzuki-ge...ear-discs.html
this setup. Not much of a write up, but the swap is straight forward. This was done on a D60, I did the same thing on my Scout D44, and the model 20 has a very similar mounting flange so it should be easily adaptable.
92 Suzuki Sidekick front rotors. Right bolt pattern, but you have to drill them out to 9/16 for the Jeep studs.
88ish Isuzu Rodeo rear calipers. These look almost identical to the Nissan ones mentioned in the post and I think a lot of the import calipers follow a very similar design.
The mounts are 1/4 plate and they bolt to the top two axle flange (retainer) bolts. I used small vacuum tube taped to the outside of the rotor to space the caliper vertically, then it's only a matter of some careful measuring. I did not have to worry about spacing my caliper to center it at all.
I've been running this set up since since 03 with no problems other than it took a few tries to get just the right MC to work.
A couple of notes: If you go this route, get the caliper end hard brake line fittings and the caliper mounting bolts from the donor vehicle. These are metric. 3/16 brake line can be inserted through the metric nut and flared just fine. The caliper mounting bolts are funny looking with a shoulder on them and probably just about impossible to find without another junk yard trip. Also grab the short section of hose as shown below. This has the correct metric end for the fitting you snagged and will also allow you to remove the caliper for service without taking a hard line loose and losing fluid.
I started with a 69ish Camaro MC for 4wdisc, then tried another application that I can't remember. Finally I swapped in a dual diaphram booster from an S10 Blazer and just for fun left the MC from that on. Worked great. Since the rebuild with the YJ tub (and booster) I am now running a 1978 Mercury Marquis 4wdisc MC. GM MC's wont bolt up to a YJ booster, but Ford stuff does..
The Merc MC is working great.
Here's a pic of my axle set up just prior to install. I would highly recommend it.
Calipers $65... had to replace one cuz it was packed with mud (45 w core)
