Default 9 inch question

I am buying the 9 inch from EPP and im just going grab a center section from the junkyard or off ebay for the time being. But my question is when i order the rear end and get the axles. I would like to get them to come with 33 spline axles but how much would it cost to make the center section adapt to the 33 spline axles?

You only have a 28 or 31 spline option with the Moser 9 inch for use with a standard style of center section. Now if you went to a spool or a locker you could go with the larger 35 spline axles. Bob

Can you use a junkyard center section with aftermarket gears/spool with the 35 spline axles?

If you can find a 35 splined 3rd member it will work, but you may have a problem finding a 35 spline at the yard with the gear ratio you want,then hope all is good inside, to be honest there is no better thing to do then get it new, when you can afford it, Bob @EPP is a good guy ask him he will tell you the truth about used parts

Most people never have a problem with 31 spline axles. You are always going to find someone somewhere you has broken something, but in general the 31 spline axles are going to work out just fine. Bob

So the center section has to be set up for 35 spline axles even if you replace the internals with a spool/locker and ring and pinion? I thought the only thing that matter was the axles and spool/locker being the same spline count.

It's pretty much like teeth on the end of the axleshaft so your traction aiding device (i.e. limited slip, locker, spool) has something to grip onto to turn the round axleshafts.
