I know the thread hasn't moved for a while, but I haven't actually stopped working on this. I figured me fettling a couple of mm off a piece of MDF, or painting the cab interior wouldn't be of much interest so I didn't bother to post. I offered up the CP for a trial fitting and thought I'd post a pic.
The eagle-eyed amongst you will notice that in the earlier photo the stainless didn't have a protective film, but now it has. That's because it's a different panel. Turns out I had given the wrong dimensions to my father by about 3mm on the height, so it just wouldn't sit right.
In the end I decided to scrap it and had a new one made up. First mistake I have made thus far. Just a shame it had to be such a bloody expensive one.
My Minipac arrived from Ultimarc the other day, as did the remaining buttons. Just need to finish the black paint interior, laminate the sides, wire it up and start thinking about a marquee, side art and a CPO (yes I am covering up the stainless.)
