Got a chance to move this forward a bit.
Finished rear speaker mounts, trimmed up the grills, got everything mounted.
Will add some screws once I decide what the back panel for cab will be.
Got the head unit mounted and trim back on. Everything works and it sounds pretty good, considering I have less than $100 Can in speakers and head unit.
I'm not sure I have found my final color for the dash speaker grill cover. Was the factory chrome glovebox door two tone paint? Anyone have good samples of the colors? There is not enough paint left on my glove box door to tell.
Will update this thread with the overhead console completion, hopefully soon.
