Looking good and learning more and more as you work on it.
I'm working on one for my Base Commanders Friend. Did a thread on Steel Soldiers, check it out on some stuff I had to do for the firewall Resistor Pack by pass and a manual GP push button:

I'm about to do the filter conversion on it next but I'm going to use the WIX 24770 mount with twin in and out ports so I can incorporate a petcock for air bleeding.
Also going to do 90s on the fittings for this one.
