How do you tell the difference between 10b and D44 inner axle shafts?

They are different lengths I believe.

The problem is I only have 1 set of inner shafts and I have no idea which axle they go too.
10 bolt specs:
- outer axle shafts sides are 9.94"
- inner axle shafts Driver-side 19.15" and Passenger-side 35.46"
Dana 44:
- outer axle shafts sides are 9.94"
- inner axle shafts Driver-side 36.13" and Passenger-side 18.31"

Is this a joke?
If not 10 boltz are 28 spline d40 are 30
I had to ask once myself

I'm not 100% sure on the front 10 bolts but i know for a fact that rear 10 bolts are 28 spline before 1989 and 30 spline from 1989 and on. With that said i'm pretty sure that all the front 10 bolts and D44's had the same spline count just a different length axle.
Never seen a D40 front axle before
Lot's of mis-information in the last couple of posts.
Front D44's in the Chevy trucks were always 30-spline inner shafts. The front 10-bolts were 28-spline until about '89 when they switched to 30-spline, but they were a different spline cut than the D44 and different overall length so they don't interchange.
