WT stamped 346 PDB MC
 

I received my 346 WT stamped power brake master cylinder from Mike Gibbons Friday. His service is second to none! He helped me from identifying a correct one to the bleeding process.
For you guys looking for a correct PDB master cylinder for your 67 or 68 Camaro do your homework for they are being fake stamped and other things. Call Mike he’ll help ya out.
