3.90 10th anniversary VS Mazdaspeed
Are there any differences between these differentials?
I have a 3.90:1 and don't know if it came from a 10th anniversary or a Mazdaspeed, now I need half-shafts so I need to know which shafts to buy.
The 3.90 that I have has numbers cast on the left side "MA02 4 PA" and painted at the bottom in white "3818" and a couple of dash marks hand painted in white on the top that look like number eleven. It has 26 splines inside the diff.

Thank's for the info, I always assumed the Mazdaspeed had a 3.90 because of the 6 speed transmission. Found one on Ebay Mazda Miata mazdaspeed Differential MX5 4 10 1 Ratio | eBay that confirms they are 4.10:1
Due the 3.90 diffs form the 10th anniversary use the same one piece half-shafts than the rest of the normally aspirated post 99 miatas?
