Help Mounting MC

[Madsen1970F100]

OK I am asking lots of questions today so I apologize.....However. in process of piecing truck back together, I have a dumb question.....shims for master cylinder and/or brake booster. Hoe does one adjust Master cylinder with these shims. Is it suppose to be level or offset one way or another? Are the shims for the where master cylendier attaches to the booster or for where booster attaches to firewall?

I did take a fair amount of reference photos but not any close enough to the back side of MC to get good idea. Pleaes advise.

Eric,
I've worked on and owned Ford trucks for some 30+ years and never seen shims used on a MC or a booster before? Typically the booster bolts to the firewall brackets / and the MC bolts directly to the booster in all of them I've ever seen.

Maybe someone else who has seen shims used in this application, can chime in here?

Thanks. I jsut know that they were on there when I took it apart. No idea if PO put them on or what...........so the MC mounts level then?

Same here, I have never seen shims used on master or booster before.

its was probably the wrong master or booster they put on to that truck. if your truck was a 67 i would say they definetly did use the shims to take up the slack to use a 68-72 setup.
