[REAL 1]

Bretts body is by Kimmons. Very nice.

There are some differences (modest) as I understand and as posted previously between the Kirkham and SAI.

Shelby uses their own suspension components. I think the main difference is in the adjustability in castor/camber in front and rear. Shelby's is more adjustable I think. Shelby uses Baer brakes or upgrade Girlings. Kirkham uses Willwood.

Other then that there may be differences in carpet used and seats.

As to changes in body I'm not sure of the details but it couldn't be in the exterior aspects as both cars are exactly the same from the exterior. The changes may be in further finishing of some of the interior panels and wiring. No big deal.

As to the heavy duty parts and build. What I believe is being referred to is the fact that many parts are not cast but forged and the use of chrome molly instead of mild steel. Both Kirkham and Shelby are identical in this regard.

Kirkham has in essence replaced AC as Shelby subcontractor for the build of the frame and body. Times have changed. So have the suppliers.
