The Y99 option was part of the Trans Am option, so whatever option on that would not show up. But, on a Formula, the Y99 option will show $167 for full size or $158.60 for Space Saver and $15.00 for S/TIRE OPT. So, TA owners could save money again (if one looks at it that way) like manual vs auto transmissions and Rally II vs Honeycombs.
