Thanks Paul! After staring at a photo of the front end of a M3W for a bit and doing some searching online, I think I understand most of what you're saying. Pictures of double wishbone suspensions often show unequal A arm lengths with the upper being shorter, its pivot point located outboard of the lower and the upright tilted inward at the top. In the Morgan photo the chassis mounts of upper and lower arms appear vertically aligned and the "vertical" is only a bit off vertical, pointing 2" inboard of the tire as you noted. The Empire kit appears to move the upper pivot point outboard through the aluminum bracket and shorter A arm. Am I on the right track here? Ha. Pun.

I wonder, while looking at the photo, if Morgan made the geometry choice it did because of appearance - it looks more like the sliding pillar suspension on the original M3Ws.
