7.25 Spline Count

[Johnjgonzo8D]

Hey guys, I've been trying to figure out what the spline count is for my 7 1/4 diff.
I had seen a number casted on the diff. It read; 3507881.
I know everyone goes the 8.75 route, but I gotta save up before I do that, and I'm trying to rebuild what I have to keep me on the road. Thanks in advance.

Axle spline count=24
Edit Axle spline count is 25 not 24. sorry, I miscounted
Pinion spline count=27

Thank you Charlie.

Alright, I've been looking around for a rebuild kit, to replace the spider gears. I've seen that they are listed for "25 spline" diff.s, does anyone know of a good kit? or what I should be looking for in a kit.

I have some good used ones, hell I would throw in the whole thing just taking up dust here.

See my correction, I miscounted, the axle spline count is 25
