I’m in the middle of doing the hydroboost conversion on my 79 f350 flatbed, is there something that is supposed to go between the master cylinder and the booster? There was a rod sticking out of the back of the vacuum booster, and thought it was odd there isn’t one in the booster... any help/pics are greatly appreciated

yes there’s a rod and clip to hold it in. On the hydro boost. If you bought a remanufactured one they don’t come with it. I found out the hard way.

That rod that sticks out of the booster is a specific length to match the master that the factory intended to be mated with it. I tried tried mating the old master to my hydro unit, but had to mod a rod to fit. I also had to slot the mounting holes. After reading where a member had his master launch from his hydro, I never felt 100% secure with my old master mated to my hydro, and the rod that I modified to activate the master. Finally, I splurged and spent $50 and bought a master designed to mate with my year/model hydro. I now feel completely safe when I hit the brakes.
If you need to do any replumbing of the brake lines, look into the nickel/copper brake lines. I found them a joy to work with when compared to the steel lines!
I also found that having dual return lines all the way to the p/s pump helped with performance, as did the Saginaw pump. With the oem p/s pump and a T into one single return, I would loose power to the steering in parking lots when I was on brakes and steering simultaneously. I also used a simple screw **** type proportioning valve, as seen with the dark blue ****.
79 F250 Master cylinder, 2001 F250 hydroboost and PS pump. Pirtek hoses to mate metric and standard. Redrilled stock booster brackets. Brake peddle sits a little lower. Ps pump was bolt on. Master was bolt on. Stops my truck on 37” tires quick😁
I had to end up making the rod between the booster and MC to get the gap right so that the MC would fully retract.
I guess it is not exactly right as I can feel a slight nudge if I an going slow in a parking lot when I tap the brake while turning the wheel. It looks easy after it was finished
