Dimensions of original Sunburst wheels

[Daytonatim]

Hello. This is my first post on this forum. I have been a big Shelby fan for many decades. I even went as far as to build, from scratch, a Daytona Coupe that I designed about 10 years ago. Not a model....a real drivable car. But now a days I settle for scratch building scale models of cars because I guess age just caught up with me.

I stumbled across this fourum while researching some information for a model I am scratch building. I am trying to find two dimensions for the original sunburst wheels that came on the 427 Cobras.

The dimensions I need are:

1) The diameter of the shaft that the spinner screws onto

2) The backspacing on the original 7.5 by 15 inch sunburst wheels

I have tried to find this info in the forum but I have not been able to differentiate between numbers for original wheels and numbers for wheels to work on different kit car setups.

Any help sure would be appreciated.

Thanks

1) The spinner threads are 2.375"-8tpi

2) Backspacing is 3.1" (+/- .1")
