Nope, the Craftsman AA109 was made by the Double A Company of Lansing Michigan and was inferior to the Atlas in many regards, including the spindle which was something like 0.55" IIRC.
Yes, simple bushings that he could make himself... since none on Fleabay at the moment.
there is a guy on e-bay that sells a set for close to $50 .
I redid the bearings on one like ten years ago. bought a couple plain bronze bearings form the local industrial supply. Like others have said Mcmaster carr.
There were a couple guys supporting the 109 but they were also trying to retire fro the business.
Worst case scenario is pull one a part an make a drawing.
Also there are several 109 variants not sure how that effected the bearing design.
also please post an introduction in the welcome area when you get a chance.
