14 how many splines do the axles have

[SEREsolution]

I want to put a 14 bolt on my 86 k5 i found a 14 bolt on a 76 c-20 but i would like to know how many splines it has on the axles but and not find info not sure if it is like the dana 60 where some have 30 and others 35. So if some one know i would be grateful for help!

all 10.5" 14bff's have the same spline count which is 30 IIRC

yeah there all 30

For clarification, full float 14 bolts are 1.56" 30 spline shafts and 14 bolt semi floaters are 1.41" 33 spline. Check whether or not your axle has full float hubs.

before the "Small" 30 spline shaft thought goes through your head
the perpetual breaking dana 60 30 spline shafts are MUCH smaller than the 30 spline 14 bolt shafts

I only mention this because i wondered at one point also how the 14bolt was indestructable at 30 spline and the dana 60 snapped like a twig at the "Same" 30 spline count

then it was explained to me the difference in the spline sizes between the two
