I moved mine back 3/4" because that was "relatively" simple to do. This however, will still not center the wheel in the fender arch, it will just provide a little bit more clearance for slightly larger diameter tires.

Arthur,
Sorry I didn't see your post until now. All the Butlers had the same chassis with the exception of the upper diff mount, which was moved back 3/4" in the later cars to extend the wheelbase for the reasons you're all discussing. There is no variation in the construction of any of the chassis; the very substantial jig would not allow for it.
Ron originally thought there were about 30 cars built before the wheelbase was lengthened. Since yours is beyond that, obviously there were more. It was done sometime in the 80's though
That I guarantee! The 3/4" does not completely center the wheel, as you mentioned, but it does provide plenty of clearance for a properly sized tire and presents a look very consistent with original Cobras (their rear wheel was forward in the well also).
Two related parts changed as a result of this. The upper shock mount was modified to have the tube offset to the rear and the front piece of the differential stiffening plate was redesigned to take up the gap that was now there. Both of the old parts could have simple spacers inserted instead, since Ron doesn't have any more sitting around.
