New rear-end screws?

My mechanicien cannot find original BMW 3.47 differential gears for less than $650.

With my cam, the 3.10 rear-end screws are... 'way too short.

Try 70 MPH at 2100 RPM in fifth. The same as my '98 Expedition.

He is a drag racer and recommended that I call an outfit called Richmond to have the gears custom manufactured for less than $300.

I am not stupid, but I am ignorant.

Ignorance is simply lack of data.

Club Cobra is a most excellent source of data.

Has anybody dealt with Richmond?

Try Ebay UT....see if you can find a set of gears or a whole center section.....surely you can beat $650.

Could probably get you a posi center section for less with some better gearing. Let me check our stock this week.

Remind me when and if I forget
