2012 JK, is the stock DANA 30 1310 or 1350?

As per the title, i am trying to figure out which front universal joint to get to replace the ones that are failing in my stock 2012 JK Sahara Unlimited, 1310 or 1350.

According to the parts catalogue, the OE MOPAR u-joint is listed as 68476678AA. That said, I would rather order a (more affordable) Spicer. Unfortunately, i am finding conflicting information about which DANA30 version I have, 1310 or 1350. Can someone clear the air for me?

thanks!
S.

Spicer 5-7166x
For a 2012 Jeep Wrangler Sahara with a Dana 30 front axle, the Spicer 5-7166x u-joint is likely the OEM-installed part. This part is designed for the 2012 to 2018 Jeep JK Wrangler models and is known for its durability

The Spicer 5-7166X is designed for the 1350 series. It is a non-greaseable universal joint that is compatible with Jeep JK Wrangler Rubicon front axles (2007-up) and Jeep JK non-Rubicon front Dana 30 axles (2013-up) with upgraded 1350 joints.
