I've picked up 2 HS65MG for my Mini LST2. What servo horn is out there that will work with the stock or upgraded steering arms and savers? I took the HS55 adapter for the Mini T, and drilled it out to fit, but I don't know how strong the spline is. This seems to be a very popular mod, but you'd think that there'd be a piece that would work. Any help will be good.

thanks!
