October 1965 Metuchen build for me. Unrestored, but of course serviced over the last 50 years. I too have the gold spacer and the "Paint OK" yellow paint stamp above the master cylinder on the cowl. The inspector was "Adam." The only intact decal in the engine compartment was the silver service one located on the driver side inner fender apron. There were some glue remnants and outline for the "289" decal on the air cleaner and maybe a bit of glue on the driver side of the air cleaner for the Autolite decal, but maybe or maybe not on that one. No other remnants that I could find. Hood hinges are phosphate and oil, steel vacuum advance line. That's all that I can verify with my car. If you do a search you will find, as I did, that the master cylinder/cap/booster were all painted semi-gloss black as a unit by the supplier, that coolant decal has no resolution, maybe yes, maybe no; coolant bypass and clamps painted with the block so blue. You should check the assembly manual for the proper routing of the coolant hoses. If you don't have one I made a simple diagram. I got that wrong at my first show on my other car so I tripled checked it to make sure I got it right. There are lots of posts on the firewall sound deadener spray so if you go that route be sure to check out the many photos. Of course you want to make sure you are duplicating the Metuchen process if it differed from the other plants. Lots of previous posts you can search. Have fun! You have a very nice car. I am sure we'd all like to see more photos.
