I had them do a '62 center bearing about 2 yrs ago. Talked to them on the phone and then shipped the assembly out to them. Turn around time was about 2 months but I was in no hurry. Bearing when in no problem and all is good.
Just a note when shipping parts out to be rebuilt......I put a tag on the part with my name & contact info....if the box is damaged and the part is lost you'll be SOL withe USPS, even with insurance.
