Hi Q, did you close off the front cab from the rear?
Yes I built a partition between the front and back
and this is how.
first I screwed a wooden beam to to top of the bulkhead to bring it level with sides of the tub.
To that I screwed 5 inch wide plank, front edge of the plank level with front edge of the bulkhead.
Exactly above that another 5 inch plank was screwed across the roof rails.
Behind the driver, To the back edges of the planks, I screwed pine cladding, cutting to fit exactly between the lower plank an the roof. I could have used a sheet of ply, but it was easier to cut the cladding bit by bit.
A frame was made to fit in the center and passenger gap between the upper and lower planks.
I worked out the width required to give a clear view of the rear door window in the reversing mirror.
That part of the frame was clad with 1/2 in clear acrylic ( because I had some, I would have bought 1/4 inch).
The rest of the frame, was covered in more cladding.
Brass drop bolts are used to hold the frame in place.
The area between the top plank and the roof was filled with bits of left over cladding.
Behind the driver and the passenger, 4 inch thick foam was glued entirely covering the front face of the cladding. This was covered in cloth matching the seat covers .
On the shelf formed by the top plank, the outer corners are occupied by loudspeakers for the radio.
The center of the top shelf is part of a roof console screwed there, with the front edge of the console plugged into the slots in the front edge of the roof / window frame. I've mounted a radio in there so far but have yet to fit CB and courtesy lights.
The head rests were removed from the seats, if I had needed it I could have put thinner foam on to give more room behind me, but at 6 ft tall i find the 4 inch gives me a perfect headrest.
I think the foam helps absorb the noise...
