This is what I could find on production numbers for the MK3. It doesn't break down into option packages though I hope it helps somewhat. If you find anything like that I would be interested as well. Good luck.
1986.5 Toyota Supra
The third generation Supra was introduced in 1986.5 as a free standing model, officially separating it from the Celica. Whereas the Celica became a front wheel drive sport coupe, the Supra retained its image as a rear-wheel drive sports/GT car. The new Supra would continue to move upscale and become a showcase for Toyota technology. Originally slated as a 1986 model, production delays caused the model to actually be introduced mid year (hence the 1986.5 designation). The all new Supra was powered by a 3.0 liter DOHC inline six cylinder engine rated at 200 bhp. Notable features included an electronically controlled independent suspension (called the Toyota Electronic Modulated Suspension - TEMS), and a removable Sport-Roof panel (Targa top).
