Thanks to all who have responded to previous questions. I intend to report on my project when (if ever) finished. I have now managed to knock out my blinkers and radio (at least). I sprayed foam in the upper cavities around the roof, and tucked batt type insul. around the bottom of the walls, and covered with 1/4 plywood, whick I screwed in place with 1" lath screws. I saw the stuff about the loose blinker thingy, which I will check, but my guess is I sent a screw thru something, which of course I did not check first for, or managed to force apart a connection with the foam. Any other ideas as to my self inpailment appreciated. thanks, Dan B.
