I am located in MN and planning to go through the back half of the my 1970 L46 once the snow flies. I will be looking for a reputable shop to go through the rear differential, including re-gearing to a 3.70 (I currently have the stock 3.36 in the car).

Can any of you recommend a good shop in MN/WI/Northern IA/Eastern ND/Eastern SD? I am willing to drive within reason to drop-off and pick-up and prefer not to ship. I like to meet the people doing the work.

Specific to the rear differential, do any of you have hard/fast things you recommend I should avoid or make sure of machining, parts, brands of components, etc? This is a street-driven car with 392hp/413tq SB and Muncie M20, done at 6K rpm. Everything is fresh from the fan to back of the drive shaft now. Just the back half to rebuild. Or, am I better off buying a completed rebuilt rear?

Thanks,
Joel

I would suggest contacting Tracdogg. He's in the Dallas area. He may know someone up there. HE would be the guy to rebuild it, but he's outside the area you specified.

Give Mike a call at Thunder Valley auto. He's near St.Cloud. He did the rehab of my rear end and trailing arms. I put 3:70 Motive Gears my 71 vert.
