Thank you all for the help. My next project is removing the assisted brakes now
"Cobb --you can only remove the fins to the vacuum pump to disable it. You need it in place to spin the oil pump as its driven by the intermediate shaft. I guess you could get a dizzy from a gas one and hack off the top of it and clamp it in place?"
I have been giving it some though here. The MC issues are all worked out, thats the easy part.
The Oil Pump issue with the intermediate shaft. I saw PartsGeek sells these for non-powered brakes on VW rabbits and they carry the non-power brake MC too.
I wonder if this replacement might work?

I filted by 1977 Rabbit 1.5L Diesel and these populated. Heck, the MC for non-assisted brakes are there too.
