Hello,
Contact me at work .... 360-736-1141 be glad to help you out. My shop is A Glass Enterprise Inc. we are in the link section under misc. Toll free in the U.S. for everyone here in the states at 1-800-223-1141. I have helped a number of the bolters here with this very thing ... insulating the trucks and or cabs. The material I use is the heatshield material. I can send you pics of cars and trucks I have done with references. Please do this right the first time ! Keep in mind that alot of the products do not meet federal motor vehicle standards for flamability
(fmss 302) , the heatshield material meets this very well. Our family business has been in the restoration business since 1975. We stock this material, as well as complete glass for all makes and models of trucks made. Hope I can help some of the bolters out.
