Cuda SRT8 392 Gen.III Hemi

Haven't gotten the paint on the car yet, but have been making progress in more indirect ways. I've taken numerous items to the powder coater, spreading the cost out over time and packing the parts away for assembly later.

I decided since I still have my new, original S/S springs from the late '70s, early '80s that I will use them to at least get the car on the road and then re-evaluate for later changes. I disassembled the springs for powder coating and found they do not have the zinc plates between the leafs like stock springs do. I had planned to get a rebuild kit that includes the clamps, rubbers and "the zincs" but am wondering if I should just get the rubbers and clamps without the zincs.

Does anyone know for sure what the zincs are for? I would assume they are there for anti-rust purposes where the spring leafs come together and rub / chafe. This car won't be daily driven and won't get the mileage it got when new. Plus the leafs will be powder coated, unlike when they were original, with no protection between the leafs.

I'm also considering taking some leafs out of the right spring so the car will sit more level. Was thinking about making them more like a heavy duty spring set like the 440 cars had, with just an additional leaf on the passenger side.

Any thoughts and input about this rear suspension dilemma? Would appreciate it...
