I call them bottom load, as they are original shocks, not CE or team style loaded from inside. The fronts are CE /Team style, as I need those for my original first RC10 (coming soon).
Hard to say with the adapters, I easily threaded the holes with a 4-40 tap. A mild motor might be ok, but I would feel better if it was delrin or aluminum or even hard nylon. I have another set for my graphite Team car, so maybe Ill try...
