It’s crap, but it’s all I have at the moment. I managed to edit the routing for the belt on the Sprint-T.
The squiggly blue line is what drawing with a crappy touch pad looks like with the editing program that comes with Windows 10. But it does manage to show where the belt will go on the Sprint-T. You can see that unsupported run from the idler to the alternator that is bothering me, plus the reduced wrap around the drive and driven pulleys that also bothers me. It might work, might not, won’t know until I try it.
