Thats all well and good but 3 of the belts don't have a month/year of manufacturer, they just have an expiry date.

From the 2019 SCTA Rule Book...
All belts shall be in good condition and have a manufacture’s
tag with a legible date not more than 5 years old on the
label
or an SFI tag with a “Valid Until” date. The Valid
Until date will be accepted up to 3 years after the
date on the tag (i.e., a June 2019 valid date will be
accepted until June 2022).
