Not sure why the pic won’t post but the part number is Goodyear  1R11.066.  

To answer the last question …. I was trying to get the ride height correct after replacing the left side rear height control valve.

Ah, Ok, in that case then yes 11.75 is all your going to get out of those airbags. They are almost 1 inch shorter than the Firestone equivalent.
