Perfect fit and clearance. 1957 Belair wagon disc brake conversion with this booster gave me plenty of room for the V8 .

I've had this installed in my car for 1000 trouble free miles. I couldn't find a dual port master with booster combo for my 1963 Buick Lasabre. I ordered this one and installed it with little modifications

Mounted on my 51 f1 cab with the Speedway Universal Under-Dash Brake Pedal Mount Bracket. It was way easier then I thought it was going to be. I will buy again on the next rat rod builds.

I am wanting to convert my 54 Chevy wagon to disc/drum using the firewall booster pedal assembly that speedway offers, would this master cylinder/booster and prop valve work for my application?

What is the difference between this Part # 91035556 and this one # 916641205? They seem to be the same kit. I have a 55 Bel Air that I will be added disc brakes to and I'm looking for a booster/master cylinder kit for it. Thanks for the help.
