I am now offering Tri5 Hydroboost brake booster adapters. Hydroboost braking systems operate off of your power steering pump, and provide much better braking than manual brakes or vacuum boosters.
These adapter plates allow you to bolt an Astro Van (or similar) Hydroboost unit to a Tri5 in the stock brake master cylinder location. Complete hydroboost brake kits are fairly expensive, and you can build your own system for much less than a kit. A key component to the installation is an adapter that allows you to bolt the hydroboost unit to the firewall. Some clearancing of the firewall hole to accommodate the large nut is required. All other fabrication work such as linkage, hoses, etc. is the responsibility of the purchaser. All I'm selling is the adapter for mounting the hydroboost unit.
I offer the adapter plate in two versions, both made of laser-cut 1/4" steel plate. They will fit any Tri5 Chevy car, and I understand there are other applications that use the same mounting pattern (58-64 Chevy?).
The "standard" version is a bolt-in using the existing studs on the brake support that protrude through the firewall. You can orient the hydroboost such that the accumulator is opposite the engine for added clearance or at 180 degrees on the engine side if that's preferred for some reason. The upgraded "hidden bolt" version is "reversed" such that the four 3/8-24 NF grade 8 studs are welded into the adapter plate, and makes for a cleaner installation. You will have to remove the bolts from the stock brake assembly to use this upgraded adapter, but in my opinion it's worth the minimal effort. The orientation for the upgraded version is with the accumulator opposite the engine, as shown in the attached picture, but I can build them opposite by special order.
The standard version is $29.95 and the "hidden bolt" version is $59.95 plus $5.75 shipping in the US lower 48.
Attached are some pictures of the adapter plates, and one installation using the hidden bolt version.
