I figured I'd seed this generic thread by asking if anyone is aware of a good, competent technician in Connecticut that can swap out the ring and pinion on my '99 Ford E-350. It's a Dana 60 with the 3.73LS final drive, I want to swap it to a 4.30:1.

The Ford dealer can do it, but they will not install aftermarket parts. Problem is, Ford only offers a 4.10 for this truck. Randy's Ring & Pinion (http://www.ringpinion.com/) offers a Yukon 4.30 and I've heard good things about their quality (although I understand it's a tad bit louder.)

I need an installer in CT that knows what they're doing and has the tools to do it right; I'll provide all the parts (bearings, seals, etc). Last thing I need is to have the rear end dropping out of the truck in the middle of Nowhere, PA...we "can" do this ourselves (http://www.ringpinion.com/downloads/yukoninstman.pdf), but it's a thankless, time-consuming job...

Feel free to hijack this thread for any other regional technician inquiries... - GA
