I have 72 gs-455 w/factory disc/drum setup. I'm looking to replace with new master cyl and brake booster... I want it to looked the way it did when it came from the factory, or close to it. Were can get it?
You probably need something like this- http://www.ebay.com/itm/70-79-GM-Factory-Disc-Brake-Dual-Bleeder-Master-Cylinder-SS-W30-Judge-GS-/190822700821?pt=Vintage_Car_Truck_Parts_Accessories&fits=Model%3AChevelle&hash=item2c6deb5715&vxp=mtr The boosters are easy to find. You will need the one that is stamped "Delco Moraine". They are readily available on Ebay
Another option - Send your Master Cylinder to get sleeved/rebuilt and send your Booster to get re-plated/rebuilt if you want to keep original parts. White Post or Apple Hyd and brakeboosters.com can help. Just a option
