I purchased an acrylic SRT start button, from ReBadge Design and Graphics, for $15 (see photo). I am very impressed with its quality. They have many custom stick-on items for a Challenger's interior, exterior and engine bay. https://rebadgedesign.com/
Rebadge has been in business for several years. He has done all of my custom badging that I have designed Sent from my iPhone using Tapatalk
