Just want to step in here and say that if you are having trouble finding a spur and/or pinion combo that works, you can also do a little tuning to the tranny ratio by going with the narrow, standard, or wide ratio gearset options. These don't affect first gear, but that's a moot point since I assume you'll be locking into second gear anyway. Also, those optional ratios are probably a little cheaper than changing pinions...
