I have 4 wheels that appear to be a Version on of the original 10 spoke Shelby wheels. They have tapered spokes, countersunk lug nuts, and the valve stem is on the rim. However, the wheels do not have a S7MS-1007-D on them. They have different numbers on them. Please help identify.
You have a later revised version of the tenspoke. It doesn't have the S7MS engineering number because it is not a wheel that came on the Ford /Shelby assemblyline. It is a later more evolved wheel made to address some of the earlier assemblyline wheel short comings. They were made by Shelby's wheel company after 68 ,69/70 production had ceased. The countersunk lugnut hole compared to the assemblyline non countersunk lugnut hole. The countersunk valve stem hole compared to the assemblyline non countersunk .Typically a smooth machined backside compared to the rough backside on a assemblyline one . The machining helped take material away for more clearance when used on 68 Mustangs/Shelby's that had a larger front brake caliper. There were other even later versions that evolved more still and were more different then the earlier style. Sorry but they are not a assemblyline wheel.
