Default Renix to ZJ Booster/MC Questions
I went to the JY today to pick up a 96 ZJ booster and master cylinder for my 89 XJ. Got the booster, MC, prop. valve guts, and the lines from the MC to the ZJ prop. valve. (I didn't get the prop. valve assembly)

Two questions: One, is it better go return the ZJ MC for a Durango MC, or is the ZJ one comparable in performance? Two, can I keep the prop. valve from my 89, replace the guts, and simply make new lines from the MC to the prop. valve? If so, what type of flares/fittings are required from ZJ MC to Renix XJ prop. valve?

Thanks for any input!

Keep the Zj booster and master and just replacing the guts is just fine.

Alright, that was what I was leaning towards anyways. Any special flares or fittings I'll have to worry about?

Why are you changing the guts in the prop valve? Got rear discs from a ZJ?

Yup, did the ZJ disc swap on the new axle soon to be going in.
