I'd sell the what came out of the #310 car for $200 if you are interested.
I think one ram needed resealed but other then that, it worked well. Just dripped once in a while.
I guess I have a nicer pump as my canopy has been up for a couple months and hasn't moved. Granted it's new lines and fittings but the same rams that came with the car and a pump from a early 90's GM convertible.
