Interesting,bump..... (why not find stock ones,too expensive?).
So I live on oahu where mopar people are scarce ,and parts are hoarded severity piles guarded by us special forces. The reason nobody uses trailer parts is the spring is narrower cars so are the backing plates . What I have now is traction bars for a fifty five Chevy .it fits the spring s and axle tubes and the Sumner lands perfectly on spring eye only thing I got to do is relocate the shock mounts on th 55 it mounts ewa of the axle on scamp its forward. Ill post pics when I can
Ah....Good luck.

I did on my 67 Valiant. Moved the springs in .800" and put on a set of BF Goodrich Radial T/As 275-60-15s. Plenty of clearance.

I do have an extra set of the offset spring shackles if anyone is interested. $10.00 plus shipping. Bill
8.75 shock plates fit in a USPS flat rate box. They are not bad from a cost perspective.
Bust out the welder and get top work moving the shock mount. It's a time or money deal at this point.

My brother and I were based in Hawaii and would go to the drags there quite often. That was in the late 70s. I still have photos from there. Bill

The 8¼, Dana 60, and 8.75 have 3 inch diameter axle tubes. The clips (u-bolts) and plate assemblies interchange. Suggest contacting someone like Desert Valley Auto Parts
http://www.dvap.com/
to see what they would charge for the plate assemblies. The clips can be hard to get off without breaking. Some trailer stores have u-bolts for a 3 inch axle, but I'm leery of Chinese metallurgy and won't use them. They are still available from Mopar.
3491 296 Clip (4 req) 6023 019 Nut (8 req)
These are the old part numbers, so someone will need to be able to bring current. IMO, the clips and nuts from a Dakota would work.
