Dave: Is the brake pedal a Bendix? If so, get the numbers off of it, and give TRENTON BRAKES, in Trenton NJ a call. Google their number and if you cant find it give me a PM or email, I have it somewhere. They specialize in older brake systems, and have many bendix rebuild kits in stock. They even have stainless steel sleeves (with lifetime warranties) for most master cylinders and slave cylinders. They were real good people to me. They will take your credit card over the phone and ship the parts to you. If they dont have a rebuild kit, perhaps they have a complete new unit in stock. Give any truck parts house a try- just have the numbers of the parts before you call them, or take the assembly with you if you go to the counter.
As for the holes in the cab, will you be leaving them or do you want to eliminate them? If you are keeping them try to find some Monkey ****, also called Electricians Dope. Like a thick clay or play-doh. Should be able to find it at most electrical supply houses. Buy some of that and stuff it in the holes.
