Stock spline count on pinion?

[LSX_MattyJ]

Looking to order a new ring and pinion just unsure of the spline it has an option for 27 and 30 spline I’d appreciate any info thanks

27 and 30 both sound off, stock should be 28

27 for pinion. 28 for axle.

Motive Performance 4.10s:
G875410

That's what I just installed... and it fit.
