You won't need a motor mount if that's what you mean....you may need standoffs of either hardwood or aluminum to match the firewall to thrust washer distance of the plane you install it on.

If you are talking about a break in stand (mount) then all you need is something sturdy and safe to literally bolt it to. I've seen guys mount em up to large saw horses, old picnic tables, metal stands, black and decker workmate....etc. Whatever it is, just be sure it stays put while you start and run your engine. Think SAFE
