I owned a '67 T-Bird, 4 door. The rear doors were (SUICIDE) doors. I don't know what you mean by "promo" Promos are plastic models dealers gave to prospective buyers of the car. There is a big collectible market for these All 67 and 68 Thunderbird promotionals were modeled after the 2 door base models

68. 68 is divisible by 17.
1 percent of 68 = 0.681% of 68= 1% * 68= 0.01 * 68= 0.68
