i got a black shorty antenna from jon a while back and am very satisfied, i also just received my full set of polished door locks (not installed yet) but the quality is second to none. overall very nice to deal with!
Yes it was the same with the stock buttons the rears sit higher when locked, The fronts are flush the rears are 1/2"-3/4" proud on stock buttons!
The billet front buttons sit below the trim when locked because they are only half the length of the stock buttons!!
They might not be JR customs as I purchased them second hand off the for sale/wanted section of the site.
