Actually, there were 268 Pewter (11U) Formulas built in '99, including the exports. I'm not familiar w/ those RPO codes you listed (I'm too lazy to look them up, but you can; Google "4th Gen F-body RPO" to get a listing). To break down the 268 you'll need to consult CompNine.com and play with their RPO filter to determine how many of those 268 Pewter Formulas were M6 (MN6) or A4 (MX0/M30) for example. Or you could take educated guesses using the percentages of the various RPOs used on the Formulas from the breakdowns linked in my sig. Example:

Total '99 Formula (coupes) built: 1602
Total '99 Formulas w/ Pewter (11U): 268 (16.7%)
Total '99 Formulas w/ M6 (MN6): 577 (36.0%)
Total '99 Formulas w/ Hardtop (no CC1/DE4): 449 (28.0%)
ESTIMATED # of '99 Hardtop Formulas w/ 11U, MN6 = 0.167 * 0.36 * 0.28 = 1.68% of the 1602 = 27
