SH69Z28,
My 69Z came with the standard steering wheel. My car build date is the 1st week of May (05A), built in Norwood. My wheel has a "D" molded into the back side of the grip, at the 12:00 position. I assume this is an April date code (hope others can confirm).
The part number molded into the back side of the inner hub is 9749408-12, and includes a logo of sorts as shown. There where two different standard wheels used in 69; one with a smooth inset and one with grain. Mine happens to be one with the grain as shown.
Good luck finding a wheel.
