so as some of my fsb bretheren have pointed out engine/exhaust heat could be pretty damaging to my peel and stick. When I did my research I only thought about the greenhouse effect in a car (how hot they get parked in the sun) and found that in a 100 degree day that temps could reach 130-160 degrees F inside a car (things like window tint and air flow from cracked windows helps a bit but not a crazy lot). I also read a bunch of reviews from folks using the peel and stick product for cars (some of which sat in the summer sun in car shows) and no complaints. I HADN''T considered radiant temperature from the motor.... DOH!!! So I called the company and the Peel and Stick has been tested to 180*F and 120 mph winds with no negative effects. This is good news because it means I don't have to worry about the sun or greenhouse effect causing it to unstick.
WHICH brings me to a decision on what to do. there are multiple options but this is what I am choosing to do. Time will tell if I've misfigured and if so I will have to yank stuff to fix it. I contacted the engineers at DesignEngineeringIInc (DEI) and they said that their Floor and Tunnel Shield II was the perfect solution and would cover up the peel and stick perfectly. (hope they are right)
So I ordered enough for the firewall and while I was at it I ordered titanium exhaust wrap to wrap my upper exhaust tube for about 3 feet to get some of the excess heat out of the compartment.
This product is pretty amazing and should keep any significant engine heat from affecting the firewall. I will post pictures once I am done.
I went to the shop last night and put two new 1330 u joints in my front driveshaft and re-installed it with the TTB yoke on the back of the 78 solid dana 44. Driveshaft looks perfect and was easy.
While I was there I removed my radiator and air conditioner core. it looks really wild to see the firewall and transmission while standing in front of the truck.
I intend to address any surface rust starting on my core support before I install anything else. There isn't anything bad but some light work will save me headaches later.
