SSS Skids & A-arm are TOP Quality.@pappyo
The clamps used to hold the A-Arm are a loop with screw & it Does Work.
Never gave me any trouble.
"A little stronger clamp would clamp would be nice"
Over the Years I've purchased "SSS Kits" -- for-- 4 machines & Would Buy AGAIN.
UHM is the way to go over metal ( Quiter & takes the Hard Use much Better )
Buy Once it will last the Life of the machine.
