My Master cylinder was trashed... Rust was so bad, the seals were leaking, and new seals were not going to fix it. Ordered a new MC. While waiting, fabricated a bracket for the Wilwood billet reservoirs. Tired of reaching under the fender to fill...
New master cylinder comes with 22mm x 12mm grommets... those will not work with the factory reservoir. The factory (Superformance one) looks to be sized for a 10mm grommet.
