hey was going to order a spool for my bronco but i guess there are 2 different axle splines it could have. any one know which one my truck would have its a 78 bronco it has the factory 9 inch is it a 28 or 31 spline???

more then likely if u can figure it out from the tag or the stampings you are gonna have to pull the axle out and count
If you can find the code tag or the codes off it i might be able to decode it.

well this may be a dumb question but i dont think it has a tag. it should be on 1 of the blots that hold the third member in right? i found the casting numbers for the thrid member but no tag.
casting numbers might work. My 9" doesnt have a tag either.

well the 1 casting i can see is 4668A its right beside the pinion
