Replacing S cam shafts on trailer

I’m tearing into the brake system on this trailer and I’ve made up my mind, just about everything needs replaced. As of today, I’ve taken all the brake shoes off and pulled the slack adjusters off. The S cam bushings are in bad shape, as are the S cam shafts. I’ve already got some slack adjusters that are 10 spline but I’m wondering if new S cam shafts that are 10 spline can still be bought?

 

Yes they are but only by an 1/8”-3/16”. My camera skills definitely makes that one look significantly longer.

 

Best I can tell, they are the same axles. My choice of camera angle was poor. The front axle spindle has a hole in the end of it with 2 incased wires that ran out to the end of the threads. I’m not sure if it was for some early style ABS or what.

 

These are both from the right side.

 

I pop the small seals out of each side of the bushing and used a large socket to drive the bushings out. For as much wear that is on the shaft, I expected the teflon bushings to be nearly gone but they weren’t.
