Another frikken Volvo ?

[NONHOG]

Well another weekend with some progress but not near as much as I hoped for.
I found a computer box out of a burned out Mazda Navaho for free.
Turned out to be not such a great deal but it was fun making it work.
(still to be realized)
After cleaning with wheel cleaner and a brush I started working on fitment.
I found the face to be warped, no surprise. It fit the computer fine but was tight on the firewall. So I got out my high end "imported" poor man's CNC.
And went to work. Also got the chance to use that "Super Alloy Welding Rod"
to fill holes and low spots. Finished with Epoxy because that "county fair" special welding rod, while fun to use, is super hard.
Worked till late and stil have some triming to do so box will fit.

Now to decide how to seal the box to the firewall. BlackJack? 3M panel bond?
