Axle Splines

[Silverback]

My car came with a 3.00:1 open rear... I've been thinking about picking up a setup "chunk" (gears, carrier, housing...) so I could just bolt it in in the place of the stock one. Probably a locker or one of the more performance oriented setups.

I'm wondering what spline count the stock axles have so I can get something that just drops in. Is there anything else I need to worry about with the center section (I believe that if the yolk doesn't match that's not a difficult swap, I don't know if the support type... makes a difference WRT to what bolts up to it)?

Your car should be 28 spline as long as you buy one that is 28 no problem if you get a 31 spline plan on buying axles also

The center of the axle (area between the Lug studs) is hollow on a 28 spline. And solid on 31 spline find out first which you have.

Plan ahead on the final power output and use of car.

If you get into drag racing with slicks or over 450 hp or so its time to go 31 spline or more and get the axles now.

For street use or mild street strip use, 28 spline is good enough just uprade to track loc or other favorite locker and gears of choice

the other thing is the cost to convert a center section from 28-31 is really minimal. Replace the spider gears and the hat and you are done. don't even have to remove the ring gear or mess with any adjustments.

Just purchased (due to arrive today a 3.50 Trak-loc from

Don Witt of www.ohiomustang.com and he sent me these

pictures so I could tell what axle I had. Just pull a hubcap.
