Got started about noon today. Spent most of the morning tracking down a fitting, it seems ARB uses a solenoid with British threads. Found an Autometer adapter that will work, it's a compromise though, it will take two fittings put together. Viair makes a fitting that will do it in one, i'll order it and just use the other one in the meantime.
I was really surprised no broken bolts, good stuff for a 23 year old truck.
As soon as the RTV sets i'll snug it all down and plug the axles back in.
I also just got a text back about an 85 front axle, it comes with a bunch of new parts and a new lunch box locker. If I can make the time I'm going to pick it up next week.
I'm really leaning toward a 3 link front at this point. This is meant to be a never ending project, so plenty of time to decide.
