It's 7.5.
Starting around 85, the 3.73 gears were 7.625 and the rest were 7.5" Sometime later, they made everything 7.625 across the board but yours would still be a 7.5"
Any 7.625 or 7.5 gearset still fits on the same carrier as each other, as long as it's the right (2 series or 3 series carrier) so it's no big deal.
