Hi All, I'm about to reinstall the Suburban furnace in my '69 Safari and I need some help with the caulking that seals the adapter between the skin and the exhaust tube. The two screws evident in the exhaust port were covered with caulking that seals the adapter to the exhaust tube. The caulking seemed like vulkem. Just not sure about the high heat in the exhaust port. See the attachment for a better understanding of my writing. Thanks, Joy
