Looking for a Made in USA 3:55 ring and pinion for a 489 case with 29 spline pinion. I believe US Gear used to make them but have been unable to find any available online. Unused preferred. Thanks!

This website claims to have them in stock.

@Skdmark

I'll give them a call today. They only list 3:91s on the website.

Oops on the wrong ratio.
Looking up US Gear it appears they were bought out by Meritor a couple years ago. That plus the pandemic might explain why everyone is out of stock.
