Need 8 3/4 bearing retainer plates

I'm looking for a pair of bearing retainer plates from the axles on ANY Mopar 8 3/4 rear. One side has the adjuster and one side is plain. Here is an auction with the parts I want but they are a little too pricey for me. (Especially the shipping..these will fit in a USPS Flate Rate box or envelope for $5.30)
