Yea, that's what I just said in my previous statement, the numbers would be different "for obvious reasons" meaning the rear has ebrake. so now I go out and find out if the fronts will work by trial and error.
The reason I started this thread is because I have seen thread after thread on the conversion. None of them mention being able to use FRONT maxima calipers (which the only ones I have access to) but the threads date bake for YEARS. So I was wondering if over those years someone had used the front. Well, I'm gona find out this weekend if they work or not.

Back when I was considering doing the disc swap I was having trouble finding info too. Looking back through my notes I didn't find much except a list of calipers, without ebrakes, used in other kits available on the market:

78-83 Chevelle, Monte Carlo, El Camino, Malibu, Tempest, Cutlass, F-85, Pontiac Grand prix, Le Mans, GTO, Grand Am, and Bonneville.

However, I couldn't find what rotors were used with these calipers. I'm thinking maybe stock D30 rotors would work but I can't remember if they were too deep and interfered with getting the caliper mounting brackets in place. If they do fit without issue I suppose you could use stock D30 calipers as well but this is all just assumption on my part at this point as it's been over a year since I last considered doing this.

I'll keep looking and see if I can find anything on my mac when I get home next week.
'84 CJ-7: Yota axles (spartan locked front, e-locked rear) 4" BDS, 1" Daystar & 3/8" shackle lifts, 35" X-Terrains on steelies, YJ Tub & family roll bar, heater blower upgrade, 4.2L w/MC2100 & Team Rush, Warn 8274. Rebuilt 4.2/4.0 hybrid, AX15 and twin sticks/clocking ring waiting to go in.

The advertised position for a topless, dirty jeep girl has been my wife. Thanks to all that applied.

Most swaps using car calipers use Geo Tracker or Suzuki Samurai front rotors since they are the same lug pattern and are thin enough to fit the car calipers.

You could also use F150 front calipers and rotors with some work.

It all comes down to your fabrication ability, budget, etc

I know people have done swaps on full size Chevy's/broncos/and blazers using Cadillac calipers. But those all use the rears, because they use the E-brake. However the fronts may work if you don't want the e-brake? They make ready made brackets that they just bolt up to. Don't know if it could be adapted to a Jeep, but it would make finding parts easy. I was looking into it for my 3/4 ton.
