yes they can move the spacers also, AMC uses A Square pastern for spindles , and any can interchange. I can put a left on a right and visa verse . so why can't you change caliper mounts from right to left. AMC was very much about adapting,

Sorry this is for another room \
but what can I say 
AMC had a very limited budget . so they built parts to mostly interchange , they were smart with thier money . so parts will be interchangeable . They were and still are way ahead of the other 2 . BIG 3 GM, ford/ ?  
Chrysler /Dodge  got billions of $ and made the Kcar , and bought AMC . they still use some of the tech From them

You can flip sides, HOWEVER; correct shim possition is on the trailing end of the caliper, not the leading end. If you flip side shim location and load direction change.
 
So, instead of the caliper being loaded directly into the bracket, now it's loaded into the shim and spring and then into the bracket. Both of which were never designed to take the force of stopping the car. They are only there to take up slack and permit easy removal of the caliper.
 
You can physically mount them to the rear, however; load won't be distributed safely or correctly.

Torisional load into the suspension is the same whether it's mounted forward or backwards.

And what shim would that be ? 
look up calipers for a 77 hornet and caliper for an 80 LTD ford . they are the same just left is right and right is left . 
Anti rattle clips are always placed on the trailing side .

Compliments of rock auto  And if you are talking about the hold down (alignment kit block and spring) Ford [I hate to keep referring to them but they did use a lot of the same part suppliers] , have used them on both leading and trailing sides for years without any problems ,

Yes, that is what I'm reffering to. I don't have a Ford  here to review the desgin but for me and my AMC, they are gonna stay on the  trailing side of the caliper. You have to remember, the block end is where the caliper comes out. Last thing I want to do with brake parts is load them in the direction of disassembly.Wink
 
Ever notice pressurized airplanes open from the inside...LOL

Yes and the ones I switched I also drilled and taped  for the pin on  the trailing side just to be safe .

I thought about that but the other side is machined different on this set.

...because it's not true.
I posted some links and quotes a few weeks ago on the very topic. Plus, it doesn't take a whole lot to find the facts on performance brakes from some folks who design/engineer them.
Too much mis-information here, sorry. But some of it was good for a chuckle.
In many cases, it's a pure matter of space and clearance, in other cases, it's how the braking impacts turns, being front or rear mounted, loading the bearings, steering, etc. But it's not center of gravity or to shift weight to the center.
 
I'll do a search and see if I can come up with the post that had the info in it. There were some links if I recall, quotes from sites, one from a brake engineer himself.
tyrodtom had info that's true...... but then that's no surprise to me.
And like was posted - check the Eagle and other later AMC listing - the calipers on my Eagle would mount either ahead or behind, depending on the bracket. They interchange. The bracket makes the difference. (Eagle also used different style calipers, depending on the year, for example, the ones used on 81 SX/4 won't fit 82 SX/4 even though the rotors are identical)
