Amongst the many things the "Toaster" needs is both the thermal acoustic liner for the 'doghouse' and the heat resistant weatherstripping that fits around the edges to seal it to the floor of the cab.

would any of you care to advise me where I can obtain replacements?
thanks very much.

Try J.C. Whitney. They have a couple thicknesses of heat-resistant sound insulation, & a variety of rubber moldings. The moldings are not likely to be specifically heat resistant, but there should be an appropriate shape.

Last year I lined the interior of my doghouse with the heat-reflective sound deadener material from CW...kit is enough to install a double layer, plus the stationary lower sidewalls of the engine compartment...Sure made a difference....

My doghouse lid seal came from Home Depot..It's the bulb-type rubber extrusion designed for the bottom of garage doors....Mounted it to the front, fixed walls too. (angled sides in-line w/ hinge) So far, (4k mi) no rubber deterioration from heat has been noticed.

Moving the bungee-latch catch about 1" higher up on the doghouse gave enough extra tension to keep the new rubber snugged down flat for a good seal.....

For 454 folks (probably 460 too), I recommend this upgrade...low tech, low cost, uncomplicated, and you WILL notice a difference in heat transmission & sound levels.

NOTE: While it will result in lower temps on the coach side of the doghouse, it doesn't mean high doghouse temps are ELIMINATED, just REFLECTED, and its gotta go somewhere. I think faithful adherance to a cool-down idling period after a hard run is even more important after this mod. .......In my case, I installed a small, 6" pancake fan on the rear fixed wall of the engine compartment, with a spring-type mechanical timer next to the hold-down bungee...gives me 5-15 minutes of run time after engine shut down...I like to think it destratifies any potential hot spot build-ups under the doghouse. If it's overkill, I'm out less than $25 and two hours of tinkering - not exactly a budget-breaker.........

I just lined mine with aluminum floor underlay designed for laminate floor installations on top of concrete. I'm sure any flooring center would be able to provide you with some remnants. I happened to have some left over from a reno job and it worked great, a huge difference in noise reduction. I put stainless staples in my staple gun and just stapled the liner to the wood. It was cheap and easy.
