After market axles will work in all 3 carriers. 741 , 742 , 489. Green bearings the axles will not use bearing adjusters so the axles will have to be trimmed to fit if they are to long.

Also BBP axles when used you will need the BBp backing plates, BBp Drums, BBp park brake struts and BBp brakes,

If drilling your axles ? You need to put the fixture on the axle turn it clockwise until the lug hole in the fixture sees the large hole in the axle and mark the axle, then turn it counter clockwise until you see a lug hole in the axle and mark the axle. Move the fixture back until you are a the center of your marks. This is where you drill for the new studs. Drill and tap the axles for 1/2 20 race studs. This will leave more room for the holes to be drilled.

Remember when using your small bolt axles with BB wheels you will need to use 3/8 spacers to keep the tires from hitting the leaf springs.

SBP brake bars and parking brake struts work just fine with BBP brakes, as long as they’re for 10” brakes. Backing plates, drums and shoes don’t interchange.

E-Brake help please

Whether or not spacers will be needed depend entirely on the size of the wheel, backspace, and tire being used. SBP axles and BBP axles do have a different flange offset that increases the rear track width when converting to BBP axles with the factory offset.
