Happ 58-91XX-L Push Buttons

Do you like Happ buttons? Oh, you do? Great! Help me get this shit outta my house.
I have 3 blue (2 concave, 1 convex), 5 red concave, and 1 yellow concave lying around. Comes with whatever cheapass switches I have lying around. One man's trash is another man's "okay I guess"!
