Hello,
I bought a very rusty 1988 Ramcharger 100 yesterday to plow with and i am looking for a backing plate for the left rear and none of my searches bring anything up. I found a GM one that look look similar but i am not a big fan of guesing.
Thank you for any assistance you can provide.

Might want to look at rear disc conversions. The backing plates don't show up anywhere, unless you get lucky on Ebay.
