Master Cylinder rebuild kit for 1968 Chevelle four wheel drum
 

Raybestos kit that was in my 68 El Camino when I purchased it.

I converted to disc/drum big brakes all around, so never used it.

Free. Actual shipping with Pirate ship. Less than $10 for sure, probably closer to five.

Part number on the box is MK472.

I am certain it would fit others vehicles in that time frame. Do some research to be sure.
