I just left a prior review concerning the fact that the Master Cylinder I ordered will not fit my OEM 1972 Ford Econoline E200. I have just discovered that the adaptors supplied with the Master Cylinder are supposed to rectify the issue I originally complained about. Now these are fitted I have discovered two new issues: 1. The adaptors, when tightened up, crush the outlet bores in the Master Cylinder, not to the point where they're useless, but creating lots of metal shavings in the process. 2. Now the adaptors are fitted, the hood on my vehicle can no longer close, it is fouling on the brake lines, as a result of utilizing the adaptors! RockAuto, with NON-EXISTENT Customer Service, leave me only this avenue to raise the matter. I am now out of pocket to the tune of $56.00. I have a useless part, and RockAuto could not be less interested. These guys are not worth trying to save a buck or two. I will take my original Master Cylinder and have it rebuilt locally, at additional cost.
