Rubber Pad on 8 3/4 Spring setup?

Here is a link to this product...

With a HUGE caveat... these are for 1070-81 GM F body cars (Firebird, Camaro). I'm not trying to imply that these will work on a Mopar leaf spring. They might, but I'm not saying that they will. I only included that pic to ask if that is what the OP was talking about.

In the OP's pics, it looks like there is only a pad on the lower side of the axle, unless I'm seeing it wrong.

Looking at Jimacuda's pics, these 2 sets might be a possible fit...

3.6112 | Chevrolet Camaro | Multi-Leaf Rear Spring Pads | Energy

ONCE AGAIN, I AM NOT SAYING THAT THESE WILL WORK WITH A MOPAR LEAF SPRING WITHOUT SOME SORT OF MODIFICATION!!!
