Got my disc/disc master cylinder and prop valve today and got them installed. Didn't do a very involved bleed and the brakes are already better. I'll do a pressure bleed this weekend I expect them to be really good then.

However, during the test drive I got it up to 50 or so and found I have quite a driveline vibration. So either I set the axle angle wrong, or they didn't do a very good job on my driveshaft. Any bets on what it will be?

I have a few sets of angle shims from when I lifted my Cherokee, so hopefully I'll be able to tune it in if its not too far off.
