Hydroboost Mounting Plates

Thanks for the response. I ended up heading to the local pick-a-part and got a unit that I could get the retainer star, pushrod and spring. So now I'll send back the junkyard booster and get the core charge back, which is basically what I paid for it at the yard.

I'd be interested to know what people did for sealing the ring gap around the booster and firewall hole.

Here is a link to my new website and online store where you can see and purchase all of the products that I fabricate for the '60-'72 GM trucks.

Do you really need to booster adapter? What is the best way to install the hydraboost? flat to the firewall or with using the booster adapter?

Torn about what looks best and what is the best way to install it also flat to the firewall does bring it closer to the firewall by the depth of the booster adapter

what is the consensus?

Using one of my booster bracket is the correct way to install a hydroboost. This is because all of my booster brackets utilize all the factory bolt holes to bolt directly to the pedal bracket on the inside. This is an important safety feature ignored by many people. Then there is the fact that with the booster bracket being at a slight angle, that keeps the hydroboost pushrod in a more straight line when moving the attachment hole in the brake pedal down 1". If you were to bolt the hydroboost mounting plate directly to the firewall, you will have to drill 4 new bolt holes in the firewall and who knows where those will end up on the inside. And then you will have to hog out the center hole in your firewall to accommodate the large nut that secures the hydroboost unit to the mounting plate. Then the hydroboost pushrod will be at a slight angle when moving the attachment point on the brake pedal down 1". This creates a side loading effect and can cause premature wear on the hydroboost unit. So you see there are good reasons for how I design my products, not just to try and sell more products.

Thanks for the explanation of why is it best to use the booster bracket.

It all makes sense when you see the details, plus the less work I need to do the better to make it work.
