So my backing plates are really rusted to the point my springs pop out of place and they lock up. Are there easily accessible backing plates from a newer civic that will fit my 87 civic si? Is there a way I can update the parts without switching to a newer rear axle? Any input would be appreciated I did read on RPR that the alum drums fit backing plates from 88+ models so im assuming that I can easily switch all my drum parts to like a 90s hatch set up and it should work fine? Thanks!
