    Anyone know if a JB7 master will bolt onto a stock K5 power booster? I have seen posts saying yes, it will bolt right on, and no, it will require the JB7 booster.

    My master has a small leak, so it needs to be replaced, so I figured if I could upgrade....I should.....

    I have an 86 K-5, and was considering a master from a 86 K20 with JB7 brakes... From what I can tell, the difference, if any is booster pushrod length, but like I said, some have posted that the 3/4 ton master swap is a bolt on deal....
