That's what I was thinking but I was hoping someone out there had already done it and could tell me a good truck to steal one off of or look up when I go in the part's store.

I imagine there aren't too many trucks that used larger bore side mount dual reservior units out there.

Bore is 1.125" correct? (I know-I can measure...)
Was master cylinder the same from 1/2 ton through 1 ton?
Do I need to try and match up stroke as well or is it not very important?

Thanks!
