A-Body leaf spring bushing challenge.

Still working on this. The Eaton Spring tip, combined with Gerald's info may have helped. On one of the many sites I've been to today after searching the Eaton part number (RB109) I was able to find an actual cross from the Chrysler number (2539127) to the RB109. Then I found that the Rock Auto listing for 6 cyl is unique to 1970 only, but different from the one for V8's. Another incorrect listing since they should both be the same, but I'm encouraged about the 1970-only thing. I ordered those from Rock Auto in addition to another set of the ones I already have but lost the bolts for.
Wanted to stick with Rock on this because they almost always ship same-day and priority mail and there's a lot more to this whole story than I originally told you guys so I need to get this done quick.
I'm happy to keep listening but for now if you guys wanna hold-off on any ideas I should wait for these next orders to arrive and go from there.
THANKS AGAIN FOR EVERYONE'S HELP
