My reserve Kia U-joint was supposed to arrive last Saturday. It finally showed up today. USPS is a little slow these days, eh?
Anyway, the Kia joint is 16mm but it's 36 spline like VW and Porsche. I don't know what out there would be 60 spline except for maybe an OE VW Polo joint.
It is 1/4" shorter than the 911 joint, which may be useful once I get into it. We'll see.
