Found some pictures of NOS 3652344 side gears and they show as 16 tooth/17 splines. Also found some pics of side gears with 10 splines and the box says for passenger cars so I'm thinking the guy selling the axle 3652342 with 10 splines for a truck has the wrong pn. The diameter of the shaft at the splines is smaller than what a truck axle should be which further convinces me that he is wrong on the GM pn. Still looking for a replacement axle 3652342. Thanks for the help.
