Well, I needed some rubber "boots" for my switches on my mxt and whites sent me a few of them free of charge! Shoot them an email or call to ask about the feet. Radio Shack sells rubber feet I think and I have some foam that will work if you want it, just have to wait til Tues to send it, Jhar
I got a whole card of feet from an electronics store. (Feet stuck onto adhesive backing) It is a common item for home-builders of electronics and radios..I would imagine Radio Shack will carry them. If not google "Electronic Supply Stores"......My Quantuum was missing two feet and I found some about the right size in my parts bin....But if you can email whites and get a pair, do it!
Whites sent me replacement rubbers for the armrest for free which was nice.
I still have the original rubber feet on my XLT but there is the drawback that they can make some control box covers gape a little so would not bother with them again.
