I think the pitman arm & shaft has 1 larger spline to only go on 1 way; i
have changed gearboxes by myself;(not fun) put at least 1 mounting bolt
thru & use long ext. bar with socket, lift st. box up with left hand &
push 1 mt. bolt thru w. right hand to start 1 bolt; that will hold the
weight, then the other 2 bolts are easy; if you leave the multi. splined
end of the flex connector on gearbox, it should still be in alignment or
close; steering wheel alignment can be made by equal adjustments on Both
sides of tie rods, or removing St. wheel?
