Hello Bob,
Thanks for the response. The 3.8S/420G wishbones and axles are intermediate between the XKE and the XJS. I forgot the specs because it has been so long since I researched this point, but I have used them uncut because they are fine widthwise.
The shock mounts are further outboard on the E-M frame to match them, and of course the lower mounts are further out on the wishbones than the E-Type. This puts the rear hubs an inch or so further out toward the center of the rear wheels.
Since I don't have the exact measurements I can't do the simple geometry. Intuitively, since the shocks are mounted a little further outboard, the stroke probably needs to be a bit more. It would be closer to the wheel, and therefore closer to the wheel travel, if that isn't too opaque a way of putting it
I'm off to see if I can swap these in - they're too dang expensive to just pitch and replace!
Regards,
Tom
I'll
