I got ahold of a Nodular Iron Case and I'm building that into my Track Rear. I have a set of 3.89's for it, what would be a great Spool for it?

I have 31 Spline Axles..

Here is a spool that I would recommend on eBay:

If you are interested in used stuff I think I have a used 31 spline spool at the house. Just email me at john@motorsports-media.com and I'll check.

For new I'd get Moser or Strange probably.

Cool, thanks. What kind is the one you have?

I'm running a strange spool in my 9" with 31 splines and it works great, no problems at all with it.

Double check your bore size on that case. It should be 3.062 for a 31 spline spool or differential.

Are you talking about the Pinion Support Bearing size?

Differential bore size in the case or center section.

I don't have it with me at the moment..I know that the Screw-in Adjusters are the same size as the stock 9" Center that I got with it.

I got two compete 9" Centers off of a kid on Craigslist for $65, one was the Nodular one so I kept that, the other was stock so I kept all the bolts and stuff and scrapped it.

The 31 spline spool that I linked you to on eBay will fit both a 2.89" or 3.06" case, but not a 3.25" case. If you have a factory center section case you are good to go, as they did not make a factory 3.25" case. If you have an aftermarket center section case you need to make sure that it is either a 2.89" or a 3.06" case.
