OK, thanks. I know that already. As I said, 16" is too short, 17" too long. For max window clearing, 16.5" is best.

Went out today and actually found an aftermarket 16.5" replacement (marked as a 17"). It appears that each manufacturer makes them a different size, so a 16" I found actually measures between 15.5" to 16.75". Weird, stupid, but true.

And found a 12" rear wiper replacement (OEM is 10", but 12" fits better and clears more rear glass.)

Done.
