Looking for recommendations on a new style master cylinder for a stock Bronco brake booster and bracket. Ideal something with plastic reservoir and good sealing lids. I have a stock 1977 setup with brand new master cylinder, it just won't stop leaking out the top. This is the second one with issues.

Trying to find a specific new part that will work with the current setup. I know there are a ton of variations with push rod length, bore size, etc. Figured someone may have found a good candidate for swap.

Thanks

I am just about to install the billet master cylinder from Tom's. It has a lid that is held down by 4 machine screws instead of a wire clamp and it will hopefully solve the leaking out the top issue that I also have. I think I paid about $90 for just the MC

If you don't mind slotting the holes slightly for the narrower Ford stud spacing, you could run the Ø1" bore master cylinder from a 2000-2005 S10 Blazer application. It has an aluminum body, plastic reservoir, screw-on cap and conventional 1/2-20 and 9/16-18 SAE inverted flare outlet ports (reversed, so front to back and back to front) and can be purchased with the outlet ports on either side, as their is a LH and RH drive option available.

Left Hand Drive (Engine Side Outlet Ports): GM #89056528, ACD #18M973, Raybestos #MC390571
Right Hand Drive (Fender Side Outlet Ports): GM #89056529, ACD #18M974, Raybestos #MC390572

I've used these on a bunch of pro-touring muscle car application with good results, and don't see why one couldn't be adapted to an EB relatively easily. These run the somewhat common Ø37.5mm [Ø1.476"] register diameter, shallow input rod depth, etc.
