There may be something odd about the 10 x 1000 that you got, because
the 9.5 x 1000s that I've always used fit perfectly. 9.5 mm is almost
exactly 3/8", so my guess is that our belts are actually 3/8" x 1000
mm, with some makers marking these as 9.5 x 1000 and some rounding up
to 10 x 1000.
On this same note, 1000 mm is 1 m, which is 39.37", which explains
why 3/8 x 39.5" belts work pretty well.
