I used Mitchell Differential Service in Shrewsbury, Mass. to do a gear swap. Excellent work, good price, and a family owned business that knows customer service. They also build custom rear ends and driveshafts too.
They do good work when they use the right parts. I had my bearings and seals replaced in my 71 skylark I brought them the axles they used Jeep ones by mistake looked the same when I bolted it up all sorts of play. I am lucky I did not drive it I would have blown the rear end right out. Everybody makes mistakes and they made good on it so I would use them again. Bill
