I have a '78 half ton with manual brakes...they asked me that **** too when I bought a master cylinder...I just picked one, I think i got whatever one they said had the biggest diameter...it works fine.

You can look on your build sheet if you can find it. Mine is on the glovebox lid and there is one under the seat. It will tell you all the build options your truck has.
