I finally had time to look for one and am getting it tomorrow. It is the only one I found in the area for sale. It is off of a 6 cyl. W108. I want to measure it before paying for it.
From another post Rod said "With the top control arms off measure between the mounting points . If it less than 806 mm the axle is bent and needs replacing." I'm sure to others that is clear. To me ... The upper control arm mounting points, the subframe mounting points, or something else? Am I measuring from the center of the mounting point or the closest edge? Will it become obvious when I see it out of the car?
I won't go into "Buy one from a W111 (used ones are normally OK and free)" as mine was used but clearly not free.
Stanford, Here is the diagram from the Service Manual, 33-0/8. The measurement is between the mounting bolt holes on the inside of the towers. 403.8mm+or-0.5 on this diagram - the top measurement. So 806.6mm is the minimum. Art
