It is a Ford 3400 unsquidly.
The shock absorber you mention is the top link sensing unit, which probably senses the draught control of the hydraulics, the unit will have a heavy spring inside the cover and through linkage will be attached to the inside workings of the hydraulics, you can cut off the broken socket and weld a new bushing onto the shaft, I would have a nice solid bushing made with more wall thickness than what that socket had, you may be able to weld that insitu, see if you can rotate the shaft against the spring pressure and if you can then Bob's your Uncle.
