Turns out you can get exact replacements for the Dzus fasteners that are used all over the place on TMC equipment, but mainly to attach sheet-metal covers to chassis. Both the screws and the securing rings can be obtained from Aircraft Spruce of Peachtree City, GA. Phone: 877-477-7823 (www.aircraftspruce.com).
Bruce has successfully reproduced the nameplates that are often missing on TMC equipment, having been removed in the de-mil process quite often. If you can obtain an original tag, and can either spare it for a few weeks, or make a very high-quality color scan, then it can be reproduced by Aluma Photoplate (http://www.alumaphoto-plateco.com). Here's Bruce's comments:
Reproductions of the original TMC (or any other manufacturer) ID Plates: Aluma Photo-Plate. Phone: 1-866-579-9096. Aluma does great work; you have seen some of the reproductions they had done from the TMC ID plates I had submitted to them (I have, and they look great!).
