I have a non posi rear end from a 57 Belair. I recently replaced the wheel cylinders, shoes, installed a new spring rebuild kit, and I will throw in new axle gaskets and spring perches as well. It has no drums and needs a new front seal. The previous owner was a little heavy handed when grinding off the original spring perches, but I don't think it would be an issue. I never got the chance to install the rear before I sold the car (47 Chevy) with it original drive train. All replaced parts have never been used. Not sure of gearing. If interested, email me at kruic1111@gmail.com I can send pics. Price is $250 obo
