Thanks for the replies.
Jim, I have the Osborn paper copies of the assembly manuals. Extremely difficult to read without a magnifying glass and even then it's a pain for these old eyes. Maybe the digital reproductions are better? But yes, only deadener is mentioned, but wanted to double check.
My car is on blocks 2' off the ground. I'll have to think on this as far as removing the undercoating. I'd like to get down to metal but man, what a job without being on a rotisserie.
Jeff, I did check the unrestored threads for Dearborn, and close to my build date, but didn't see anything with undercoating so felt a confirmation was required. I don't think a separate thread is required as its a pretty clear, do I remove or not, issue for me.
Where can I get the MCA guidelines for the various classes? I'm a member of the local chapter but they don't have any links on their website. Actually their website has been down for the last while.
