Overall Assessment

The product is a high-quality Master Cylinder/Vacuum Booster that offers easy installation and marked improvement in vehicle performance. Despite requiring minor adjustments for certain models like the 1969 Falcon Wagon, the part generally fits well, specifically on model years 1966 and up for Falcon, Fairlane, Comet, and Ranchero. The enhancement in brake mechanism is prevalent and customers are satisfied to the point of recommending it for other projects. Some customers have suggested that it would be even more user friendly if it included adapter brake pipes and more detailed instructions. Overall, the booster is a well received upgrade, often praised for its efficacy and compatibility. It stands out in its category, endorsed by customers for its excellent quality and effectiveness.

Fits Falcon but needed modification.

I ran into an issue but I may not have the right application. I was told that the 1966 and up fairlane,falcon,comet,ranchero all share the same components but I ran into a problem with the master cylinder hitting the shock tower on my 1969 Falcon Wagon. I had to shim the bottom of the booster bracket to get the m/s to raise up enough to not hit. Installation was a breeze. Make sure to measure the push pin sticking out and the depth of the hole on the master cylinder. Needs to be as close as you can get it without it touching. About 15-20 thousandths. I used the factory proportioning valve and drum/drum master cylinder and the lines had to go over the shock tower but was no problem to make. Works great. Almost too good. Would buy again for other project.
