Not a huge update, as i'm back to work again, so i'm only able to pick away at this thing when a few spare minutes pop up.
Spent a bunch of time getting the power supply and battery box sorted out. I'm making one deviation from "As Issued" with this thing, and it came in the form of a Master Switch/Battery Cut-Off.
The Dash Switch on these things isn't really a Master Switch, as a bunch of things still work when its switched off (Starter, Lights... etc etc), and most 151 Owners complain of the batteries going flat when its been sitting for a while, most likely from a small power draw somewhere in the system.
Anyway, I spent nearly an hour trying to figure out where I could mount this thing in manner that looks somewhat correct and is functional. I'm not worried about hiding it, thats what the SWR Cable through the Steering Wheel and Clutch Pedal is for

I ended up putting it within the seat riser on passenger side, as this puts the connections right in the battery box and out of the elements, so I don't have to start fooling with running cables all over the place:
Lastly, since i'm always worried about wether or not I got the paint right, I finally got some validation today. I took the empty instrument cluster from the old 1 Svc Bn 151 and just gave it a real quick scrub (in the middle) with some soap and water and let it dry..... Not bad at all. I think i'll be able to live with my 383 Green base coat
