Following up on my last post, I managed to find a cheap tow hook on eBay that actually fits. Here's the item info in case someone in the future needs help to find it:
Thread Dimensions: M21-2.5 x ~23mm (very weird I know)
Brand: HQS (probably 'High Quality Store')
Mfg. Part #: T049-TH07RD
Compatibility (according to the seller): 03-11 Infiniti FX35, 08-11 Nissan Versa , 08-11 Infiniti EX35, 09-11 Nissan GT-R
Seller: highqualitystore08

Hope this is helpful to all my fellow Versa owners who just want to have a tow hook that fits!
EDIT: I drive a 2008 Nissan Versa SL hatchback from Canada, just in case anyone runs into fit issues.
