Hello to all. Quick question that I could not find in the searches. Can’t come up with the proper search words I guess. Anyway, on my 1977 FJ40, I know that there is felt, soon to be rubber under the gas tank, but what about between the top of the gas tank and the underneath of the gas tank cover. I looked at SOR’s micro fish and it shows two unidentified long strips of what appears to be some type of padding. If you have put something between, please let me know what you used and how thick it is. Thanks as always for all your time and knowledge!
