A1 trailer/park assembly

[Lmtv772]

has anyone changed out the two air valves in favor for the upgraded rebuildable combined assembly?
If you like to to that upgrade, I worked it out how to.

This is what it looks like. I love those new push in fittings that the later model truck come with
NDT was a great help in sorting it out, thank you , sir

I want to do this on mine eventually. Did you basically match up the port descriptions to know which lines to hook up where?

its not quite as simple. The old valves have hoses connected all around them. On the new assembly the ports are on the bottom side. So you'll have to sort out what goes where , which port needs to vent and which one to block.
