Customers appreciate the product's easy installation, especially notable since some aren't professional mechanics but hobbyists. It fits well in a Mustang of old vintage, and even comes with adjustable features like the booster pushrod, though some adjustments may be necessary for optimal performance. Quality of materials is demonstrated through the product's reuse of existing holes and replaceable brake lines. While it may initially be a bit time-consuming and complex, ultimate engagement is assured with the appropriate tools. Customers recommend the product for its practicality and usability.

This was an easy installation for my 65 Mustang. I replaced my 56 year old brake lines so I cannot comment on what it would take to reuse the existing. The existing holes were reused. I did need to get new bolts for the fire wall adapter since I was replacing a 2 bolt factory unit, simple drive to NAPA. - Oh - I am not a mechanic, just a hobbyist.

The booster pushrod is adjustable but even in max out condition and using extension shipped with booster, was too short to get proper MC engagement. Had to remove their extension screw and fabricate a longer one from a metric SS screw to get proper engagement. Do yourself a favor and purchase the depth checking tool to ensure proper engagement. On a 66, this is tight and a PITA to R&R.
