Leaf Spring rear shackle Sleeve NEEDED

[DartGTX]

Hello All, I need a sleeve for adapting A-Body leaf spring shackles to SS springs with a B-Body bushing. Already have both A (1/2" ID) & B (9/16 ID) body poly bushing sets. Need HELP!

Shackle shaft is 1/2", Bushing ID is 9/16" anyone have an EASY answer? can be any length up to 3" long.

Thanks, Chris
