looking at my stuff it looks like the bearings I got are for an 8Ba.
I think I need the 81a-6331 style.
Am I right

Hi Lawrie, if there's anyone in your area with a decent lathe you will be able to use that set. Not all that difficult for a good machinist?
You need to remove .015"/.016" from the backsides of the thrust surfaces on both shells. We've done a number of these over the years when the early sets weren't available/out-of-stock.
Thanks, Gary in N.Y.
P.S. Lawrie, on a side note here, this shot may help with another question you asked. These are nice pieces (stainless) considering the cost, just put another large number on the shelf.
