Hi guys-I got confirmation that the driveshafts are not the same length and are thus not interchangeable. Apparently the GTV ones are longer.
Yes, a GT has a longer wheelbase than a spider, so its driveshaft needs to be that much longer. So GT and spider (and sedan) shafts are not interchangable.

However, 105-115 shafts from GT's would interchange. The same U-joint is used for 1750's and 2L's (see:

Yes, the flanges that attach to the U joints have 9mm holes on a 2L and 8mm on a 1750, but that's not really part of the driveshaft.
