80 Hydroboost bracket mods

[plug ugly]

yea yea, I know its been talked about, but there is little for decent info and pics regarding actual bracket alterations to the factory scout bracket.

Scout is two bolt, my HB is a 4 bolt, and I ASSume they all are? In talking with Van at Vanco, a straight pushrod is fairly critical for HB life longevity. In looking at my bracket, two of the HB bolts will be above the factory 80 bracket to center the HB bore through the bracket. Not a tough task to make, just curious what others have done, and how they have had to modify the pushrod?

Urban Wheeler, I saw that you are running HB, and you said you took 3/8 or so of the pushrod. Have any pics of the pedal side of your bracket and the pushrod?

I modded the bucket thingy but have since picked up another booster with the angled mounting plate that I think would work really well if the bucket was removed and a flat piece installed in its place.

no I dont think I saw that one. I did see another with you and urban talking about it.

anyway, it looks like their is HB with just two bolts???????????

Im running a clutch master, so cutting the bucket like that wont work for me.

Ah yes.... the clutch master throws a curve in there. I have never seen one with only two bolts. How about removing the HB bracket and mounting it directly to the bucket the same way it is mounted to the four bolt bracket, through a big hole.

edit: for the pushrod I cut mine and sleeved it back together. you have to make sure not to put the sleeve to close to the booster or it will limit the travel. I also thought about cutting it and threading the shaft so it would be adjustable.

I'll get some pics after work.

That is how I mounted mine.

my HB doesnt have a bracket, it was designed to mount straight to the firewall in my bronco. I cut the firewall out, and traced it, so I may "try" that. Vanco's HB unit has the pushrod crimped in, making alterations dificult

:edit: the HB I used is from an Astrovan, and had studs pressed in. I knocked the studs out and had to drill 3 new holes in the flange because the old holes were on the curve of the bucket. Also, I think I had to enlarge the center hole so the HB would fit through. If you needed room for a clutch master there is room to cut the flange down if it is needed.

When I put it together I was running SII 44s. I had plenty of braking power, but the brake lines exit towards the fender. I don't really like that, so I am going to try HOS's mod and use the Grand Marquis master.

thanks urban. that looks about what I have going, even the little brake light sensor??? at the top. I appreciate you contorting your body to get those pics.

I finally figured it out, except for the pushrod. Mine is designed to go over a stud, not threaded like yours. Ill try and get some pics up to explain better.

I cut along the blue line, and it fit fine. Camera died, so no post cut pics



it actually looks like the HB an unthread from the bracket???

['71 800B]

yes it will come off of the bracket by removing the big nut. The push rod is crimped in, I just cut mine off and put it back together at the length I needed. clamp some visegrips on the shaft near the HB as a heat sink when you weld the shaft.

[Urban Wheeler]

Yeah that is the brake light switch. I didn't want to plumb in another pressure switch, and I already had that one.

I like it better than plumbing one personally.

heres what I cam up with





I hadto drillout the clutch mc a 1/16th to fit the wilwood m/c
