you could always make new brackets instead of using a spacer, i think it would look better, it would look as though the truck actually came with hydroboost.

I drive a 1978 Mercury Grand Marquis that has 4 wheel disc brakes with hydroboost and it stops very nice so I wonder how well a hydroboost from a fullsize 4 wheel disc 1975 to 1978 Lincoln or Mercury Marquis or Ford LTD would fit these trucks?

it may work, but it also may not output enough pressure.

Marquis

I had a 76 that I was going to use the Hydroboost from several years ago..ended up selling the whole car...those cars are very heavy and the unit should work just fine for a truck unless it built insanely huge....Superduty units are just easier to come by now...and a little more modern.

Of course my car is my daily driver and a nice car so I would never use it for a donor and they are heavy, it weighs 4,700 pounds.

Not to toot my own horn, but you apparently haven't seen my work. Machined aluminum will look just fine (I bought the aluminum block/billet today)
As for looking as if the truck came with one... I strive in all of my work on the trucks to look BETTER than it did coming from the factory. I think I'm doing ok at pulling that off as well.
Factory "brackets" were an L bent piece of steel. I'll take a machined piece instead most of the time.

I haven't run an old hydrobbost before but from what I have heard the new units seem to function a bit better. Plus, based on other responses here - the new ones sound a little smaller/more compact.

i am not doubting the quality of your work, i personally like things to look as they would have if ford did it. thats just my preference.

Not going to split hairs some of the things ford did was fine but other parts of these trucks you just have to sit back and think what were they smoking? The really bad pedal bushing design, firewall flex at the booster and the fuse box which uses such uncommon and hard to find fuses. So if you can find a part you can make better than stock I say go for it.

I'm confused, does one PS pump run the brakes and steering or do you need two pumps?

usually its one pump, but you could use 2, for a safety factor.

I want to drive my truck first, maybe after everything is finished with my conversion I'll take a weekend to do this job. I live in Illinois and won't drive my truck after the salt hits the road so that leaves me roughly until December to drive my truck if I ever get time to finish it.

Oh and for the record Chasetruck, the pics of your work toot your horn for you.

Gashog the prices that you quoted are the junk yard prices or did you get them at a parts store, if so where? Do you have any part numbers?
My 79's brakes were pretty jacked from the PO and my plan is to do alot of hauling and towing with 37's so a little extra stopping power would be great.
Why did you do the snap rings? If your worried about the bolts backing out way not do lock-tight or a jam nut and lock-tight. Just curious.

Thanks for the post.
