Yes I've seen other other GM car forums where someone managed to get production numbers on now many such and such, got such and such option, in that year when the exterior color was such and such. No luck here.
Important option choices in 4th Gen SS were very limited each year. Exterior colors four for the most part of production, interior colors most years two, performance option maybe only posi or not, floor shift and console or bucket seats, or cruise. My guess from the few hundred 4th Gens SS I've seen most were heavily optioned. I think my 86 black with gray, was only short the posi and T-tops when the original owner ordered it.
Two big questions on how many got what was T-top, and stand-up or lay-down rear spoiler. Spoiler issue was an 87-88 Monte SS and Aero Coupe only debate. Don't think a number ever got put on that important question.
Here's production numbers from our forum's FAQ. Accurate, could be. http://montecarloss.com/SS_FAQ_2.html#2
