OK, that was easy nuff.
just had to make tool to measure distance & and center the shaft in the A-frame. Coming along nicely for the amateur that I am. Did find out though, that the reason the left side was so terribly worn out was that some previous owner had replaced some parts on pass. side and put it together wrong. The angle and sloppiness of the rt side lower A-frame was causing extra tension drawing in on the lft side upper. The lft upper shaft was worn more than halfway through and wouldn't last much longer (the way I drive it). Glad I finally did get round to tryin to fix this.
