Non-T TBelt compatibility:10V vs 20V

[Tony Hoffman]

Count the teeth on the timing belts, there are more on a NG/NF than a
JT. I'd suspect the same on the 20v. Also, the 16v's have a wider TB
than the 8v's, I'd sort of suspect the same on the 10 vs 20v's as
well. However, I don't have any specific BTDT on it, so best of luck.
