Replacement front axle looks different ...need help

[hubdawg]

Purchased replacement front axle from rock auto, first mistake! for my 72 K5. When they arrived the splines and length are correct but there are a couple of differences , retainer clip grooves and spline length. No live customer service so no way to ask. Will these work, anybody else use them?

they'll work just fine. Aftermarket shaft for the inner. Dana shaft for the outer is universal between the years for the locking hub snap ring.
