Hello all, I have a Dana 44 I believe from a 1956 half ton truck. Tapered axles, were all of these used in Studes 19 spline? I am eventually going to get a posi unit, but I want to make sure that 19 spline is indeed what I need...Thanks!

Thanks again Mr. Biggs! Is there any disadvantage, or advantage to 30 spline vs. 19 etc? I have found a 19 spline posi system with some looking, but it seems that other mfg's used the 30 pretty regular..Not that it matters to my app, but I was just wondering why the 30 seemed so popular..Thanks!!

finer splines are stronger.

Thanks Nate!! That so...30 would be a little tougher?

I guess what I'm asking is, within reason, you can still pour the coal to the 19 spline, and be ok??

The axle will break at the tapered end before the splines have an issue, usually...
