I've called Racer Wholesale and Saferacer and they only have 2006's. I need new ones before March 10 and would like to get an extra year out of them by getting ones with a 2007 date.
If you order from them make sure you specify standard camlock, I screwed up and ordered
an english six point instead, they swapped it out no charge, no shipping cost to me.
If you order from a manufacturer (and even some re-sellers) they just punch the appropriate date on the set they take out of inventory for you. They are not necessarily manufactured in the year you buy.
Most manufacturers give their retailers a 2-3 month "freebie" to account for some time spent on the shelf. That's why the belt labels don't necessarily reflect an accurate manufactured date. Hence the March 2007 label in Feb.
