Whatever Marti is referring to, it cannot be a P/B booster. The master cylinder bolts to the booster that bolts to the firewall.

If this was an F350, it might have a Hydro-Vac, but this is a remote mounted booster located on the frame rail.

Are you referencing the two holes in your alternator bracket as missing something? They were for another adjustable belt idler pulley. Note in Bill's pic a 8678 assembly (8680,2884,2876,and 8687) that mounts to the 10A313 bracket.

It's possible that your truck was set up with AC and the thermactor pump too. You currently have the type of Alt. bracket mounted for them.

I pointed this out when I posted the pic. OP thinks this is where the vacuum pump/brake booster was mounted.

In two words: IM POSSIBLE!

Actually no that’s not what I was thinking. I was wondering what the report was refering too. I initially believed it to be the option of power brakes titled as a vacuum assist but was wondering if there was some reason for a vacuum pump for additional vacuum (such as you find on older diesels) due to the empty bracket spot. Then someone said it maybe an air pump for emissions. I still leaned towards just different wording for Brake booster. Never thought the brake booster would be mounted any where other than the MC.

When you showed me the A/C schematic I realized that the bracket was for the a/c idler pulley. That’s why I said “So that leads me to believe they [Marti] are refering to brake booster.” I was Never thinking brake booster would be installed on the bracket just a vacuum or air pump possibly.

I do appreciate the schematics as it’s giving a better picture of how this truck was originally put together. Former owner hacked it up pretty good.

"Former owner hacked it up pretty good." This has happened to so many of us, so many times, that I think there must be a book "How to screw it up for Dummies" out there in the glove box (left by the previous owner).

So I thought easy to remove right? Oh yeah only to expose he used an orbital sander with 60 or 40 grit to “give it some bite” including the chrome bumper and of course hitting all lights and trim
