My old one, it was a "quickstik" with the big stirrup handle, 52 lb thrust, yep.
You had to take three screws out of bottom of head, then there was a
quarter inch bolt cross-ways thru the head and shaft. (Inside the head) It was down under the wad of wires, sort of hard to get too. But pull it and reverse, put back in, and you're in business!
