1989 GTB Production Numbers for USA?

Came across this old thread. Does anyone have any recent data on US 89 328 GTB production numbers? Seems it settled betwee. 38-45.

 

This thread has a lot of speculative analysis, which might be interesting to read: How many 1989 328's?

Likewise, the following thread makes estimates of all 3x8 production by year: 3x8 Production Numbers by Year of Manufacture

The first thread notes that North America was receiving roughly 27% of Ferrari production at the time. The second thread suggests that about 250 328 GTBs were manufactured in 1989. If these numbers are roughly correct, that would mean there are about 250 x 0.27 = 67 of them.

 

So …. 37

But the United States did not receive the two variant in the same proportion, so the 27% does not apply. The US received about 2350 GTSs, so more than 27% of 6068; and about 135 GTBs, so about 10% of 1344.
Furthermore, the factory figures are for production in calendar years: Jan 1st to Dec 31st (actually, to Sept 30th only for 328s in 1989, as the production ended in September). Whereas the figure of 37 1989 US GTBs means 37 MY 1989 cars, so Sept 1, 1989 to Sept 30, 1989 (there were no MY 1990 328s).
