Tim,  Are ALL of the front brake components gone?  You mentioned just the calipers.  If the AB coded hub/spindles are there, they should be noticeably different, including the caliper mounting bracket, hub, steering arm, CX coded brake cyl., etc.  Some good reference photos are in John Hooper's book, page 121.  Hope you find a clue!

I put spring spacers in the front right coils which helped, but will still replace the springs.

Take a jack and support the car on a thin block of wood under the center of the front cross-member (car needs to be able to rock easily).  Go and bounce the rear body gently.  Did the rear level out?  If so, then the front springs are pushing up unevenly (or you have a coil out of its pocket). 

If not then either the leaf springs are binding or worn un-evenly.  You can loosen the bushing bolts (eye bushing and shackles).  try the bounce again.  if that does not do it, swap the leafs side to side.  Did the lean follow to the other side?  If so, that is the worn leaf.   

Leafs are new

In the Corvette applications, the hydraulic-lifter engines used the 7" balancer and the solid-lifter engines used the 8" balancer.
This applies to ALL applications of passenger cars regarding the 396 (402) & 427. All 454's use an 8in. balancer with an internal counterweight made for the 454 ONLY.

External.

Internal-meaning not seen from the external, front, outside side, meaning the weight is inside of the backside of the balancer. Only talking about balancers here, not how engines are balanced. Thanks.

In my case I blocked the car in a shop with floor anchors and found the low point at the rear subframe/rear quarter of the car. Then jacked the low area. It was tricky, The body would spring back. I had to find with a pressure gauge the point that the body gave.
It worked out good without any panel issues.
I believe the car had an accident or was made with a twist.
The previous owner replaced both front springs thinking that was the problem. I replaced the rear springs in hope that was the issue.
Still may not be your problem, eliminate all other possibility's first.
