I used the wrong axle length with my 742 3.91 clutch type suregrip. I was reading up on using C body and truck axles. How costly is it to have an axle cut and resplined? I am looking for the least expensive way to get the 742 back in action. I'm hoping it will hold up to 400hp for at least a year (without slicks)

Is that enough? Mancini racing says the clutch type dif requires a 28 3/16 axle. Honestly there was 1/4" of splines ripped off. 1/4+3/16= 7/16 that doesn't seem like enough spline contact to me How does the adj work if I DON'T go with the green bearings?

Off the shelf Yukon axles are actually 28 7/8", which is 1/8" shorter than they should be. If you remove the thrust button, you can run a 28 1/8" axle. Any thing longer will interfere with the internal cross shaft expansion in your sure-grip. Keep in mind, the axles will measure 1/8" longer if you measure them diagonally. BTW, I machine correct length axles for your application. E-mail me if you are interested. Contact info

Wondering if they will just become paper weights or if I should try and sell them letting the buyer know that they are messed up.
