CDC handling pack RSB bushings?

[5.0 Junkie]

I bought the pack due to price and just wanting 1" drop. It didn't come with bushings for the RSB. Is the M-5490-BKA kit the one I need? I searched here, ebay, Steeda, FRPP site, etc. It measure 7/8".

Or does anyone sell the bushings I need just for the rear? I couldn't find any matching "generic" ones on ebay.
