that's not a 60 series box that I've ever seen. 60 series box's use 4 bolts on the side. also with the arm on backwards you'd have to turn the wheel in the opposite direction than where you wanted to go.
I'd be wary of the frame bracing also, doesn't look like a lot of extra "beefing" up
and what kind of tie rod end is connecting the rod to the steering arm? no castle nut, kinda hard to tell if there is a cotter pin in there???
I must have been huffing glue or something yesterday. I'm an idiot. Clearly not a 60 PS box, for LOTS of reasons.
Kind of looks to me like Poser found it.
Kind of off topic, but related: are 70 series and 60 series boxes pretty much the same internally, other than the pitman arm direction? And are all 70 series pitman arms to the back, or did it change for different years/models? Anybody done a 70 series PS swap?
