Thanks Srinifin. Yes, I saw that the compensator spring will have to be changed over from the Fintail to the W108 axle. Certainly looks like it would help if that spring was compressed (such as when you are changing shocks in a McPherson strut) to aid in removal then installation. Also, when I checked my car, the rubber brake lines from the body of the car to the rear axle are longer on the W108 versus the Fintail.
