If we're talking about the 60 PS box with the factory 60 PS pump, then yes, I'd agree. However, put a Saginaw pump behind that 60 PS box (like I have) and you will have no problems turning 40" tires 95% of the time. When I'm really bound up in the rocks, I can definitely feel the need for a ram assist.
The FZJ80 PS box uses the same bolt pattern as the late FJ60 box, but has a larger power piston. If you took the FZJ80 box, put a UZJ105 sector shaft (and pitman arm) on it then used that for a PS conversion, ported for ram assist of course, that'd be the bees knees. That's my eventual plan.
I had forgotten all about the Sag pump on the CP. Man, I really do like that setup. Having to do shock hoops kinda sucked though...and now I wish I had done them inside the fenders. I get a little rubbing on them at full stuff as they are now.
