I mounted my calipers on the front with B/E body rubber hoses from Wagner. Larrry I still have my entire setup hoses and everything but the knuckles if you need it. Gus

I have this system on my car now for many years. I mounted the calipers on the rear. I’m having no issues except that the calipers hit the front shock absorbers when the wheels are turned all the way. The bottom of my shocks have dents in them. I was thinking of mounting the calipers to the front, but looks like the rubber hoses will be too short. I could be wrong, but it sure looks like it to me.

It really depends on the caliper that you used. There are a bunch of different caliper castings. Some are designed to be rear hung, some are designed to be front hung. You need to use the correct casting for the application.
Rear hung on the left, front hung on the right. If you use the wrong caliper casting then you end up with hose issues and interference problems. Sounds like you have the wrong castings. I've rear hung calipers before and never had an issue with shock interference so I'm guessing you have front hung calipers mounted on the rear position.

The calipers that are on there now are like the ones on the right side of your picture. I didn't know there were two different types. How would I order or get the one shown on the left in your picture and also what about the brake hose??? What vehicle did the ones on the left come on? Maybe just order individual parts based on that..

I actually have Diplomat caliper brackets for the bigger rotors. Not using them at this point though.

Andy, pardon my ignorance, but what does FMJ mean??? J Body on here will be insulted! FMJ are the bent bar cars. I don't remember the exact years, first started around 1976 and ran thru late 80's maybe? You have to be careful about nameplates since Chrysler reused nameplates between different platforms. Some cars were B body then R body then maybe J body at the end. If you're going to ask a part counter monkey for a part you should be safe to ask for Volare parts. I don't think the Volare was ever used on a different platform.

Another question. Can Use the existing calipers with the rubber brake hose from an FMJ model?? Assuming that the FMj hose is longer.

I actually have Diplomat caliper brackets for the bigger rotors. Not using them at this point though. Diplomat calipers would most likely be rear hung. The R body cars got the larger 11.75 rotors. FMJ usually got the smaller 11 inch. Or perhaps FMJ only got the 11 inch rotors, I really don't know for sure. But when I used to do disc brake swaps I would search for R body cars since they had the larger rotors. The knuckles off of the the FMJ cars are good for disc brake swaps. They are taller than the A body knuckles and they are lighter.

73 up B and R bodies used the caliper with the low mounted hose, this hits the shock on 66 to 72 B bodies when rear mounted. BTDT Not sure about A or FMJ calipers
If one is going to rear mount the calipers on 66 to 72, I recommend moving the frame end of the hose to a position forward of the spindles. Basically mirror image of the factory design.

I like using Rock Auto for interchange research. It may not always be spot on, but it usually gets me in the ballpark. This is what it shows for Volare/Aspens hth Thanks. These are all for the rear mount caliper, correct???

I'm pretty sure that all FMJ body cars had rear hung calipers. It has been 20 years since I was a regular at the wrecking yards but that is what I recall. according to RockAuto, the calipers are reversible.

One of the joys of ordering from Rockauto ... they don't have a freaking clue , They list 1500 shocks for RWD 2nd gen dodge 2500's. I suggest you use the local parts store to figure out what actual calipers you are getting.
running up my post count some more .
