Just a heads ups, you may already know this. Suggest you check the air pressure of the slave cylinders. Before using, as part of the set up, preflight.
That helps the jack retract fully after the car weight has unloaded, sitting on the tires.
Found a ram would loose all pressure in a day or two. Gave the schrader valve 1/2 turn, ended up removing the chrome housing. Wrapped the threads with teflon tape, good to go.
That's quite the hotRod ya have there.
Love the Quick Jack very nice and well built, I don't find them hard to slide around on a concert floor, might be for weaklings .
