Hydraulic powered snow plow for a QL? Good luck with that, I'm still looking for few years in Canada, I don't even find a manual one in good condition I can mod to hydraulic in my neck of the wood.
The OEM top ISO may last only if they are in good condition and you did the cradle mod. Using all Moog can't be worse then using solid mount but it's nothing compare to riding a old Shovel head
