These hydroboost mounting plates are laser cut from 10ga mild steel and will fit all common GM hydroboost units. As you can see in the pic it has the tang in the center hole as the OEM bracket does to eliminate rotation. These plates have the 3 3/8" x 3 1/2" hole pattern that will match up with the booster adapter brackets that I sell, as well as some OEM applications.

The hydroboost unit shown in the pics below is one from a '98 Astro Van which can usually be found in salvage yards easily. Of course there are many other applications for hydroboostunits, mainly diesel powered trucks and 1 ton trucks.

The cost on these hydroboost mounting plates are $25.00 each plus $5.00 flatrate shipping. However if you purchase one with one of my booster adapter brackets the cost is $20.00 and no extra for shipping.

To remove the nut that retains OEM bracket takes a special socket which I have and I will rent the socket to purchursers for the cost of shipping plus a $20.00 refundable deposit. Sometimes you can remove the nut with a crescent or an open end wrench, depending on the OEM bracket.

One more pic.....

Hey Cap'n...are you pretty familiar with swapping in these hydroboost units? I picked up a brand new one for cheap awhile ago and I am not sure what I will use it on. I will definitely pick up one of your set-ups when I get to that point.

I'm more concerned about the hoses and fittings than actually mounting the component. Ive also seen two Astro vans at the salvage yard...I should go rob the hoses, huh?

Hey protrash. check out the link for hydroboost adapters to AN fittings.

I haven't done one myself yet, but I have looked at several. They're really not that hard to plumb. There are a few places that sell either ready made SS braided hose sets, or you can piece your own together. I'll make sure you find what you need to complete your install. ;)

Thanx toms84ss and Cap'n fab. Ive seen the kits for plumbing and thought they were rather pricey. I will continue to keep my eyes open and will utilize your services when it comes up.

I have a BBC serp set-up with the correct pwr steering pump for hydroboost. I think this is what I'll be putting in the 'burb eventually.

Seriously considering one of the Hydroboost set-ups. Any pics of one mounted. Looks like it would clear up alot of room with the BBC in my 72. Will our lines from the prop valve tie in to the prop valve on the new valve? Have to change the length of the rod from the pedal to the booster? Basically just need to know what else is needed to make this work. Thanks man.

Unfortunately Josh I don't have any installed pics, but yes it does open up the engine compartment some, especially when combined with my booster bracket. That gets everything closer to the firewall. Some guys even flip the hydroboosters upside down from the factory position to move the accumilator (?) to the outside. You probably wouldn't even have to break open a brake line to convert to hydroboost, since you should be able to use your current master cylinder providing it is a power master. Yes you will have to graft the hydroboost pushrod to the original one for your truck. If you want to give this a try let me know and I'll work with you to make sure the install goes smoothly.
