So you are saying that the swing arm bushes/eyes are machined to the correct inderfearance fit & alinement for a needle race...
but you also say yer NOT sure what size & never had one...
confusing post....
what is needed is someone to measure them... not with a ruler or calipers..
get a snap gauge & micometer... So yer can check for round/ tapper /weld destortion
then it would be possable to see if a needle races can be fitted..
as a rubber bush even with a outer sleeve can be pushed in to any hole near the right size
but not so with a needle race...
Anything ealse is just quess work...
the japs line bore theres after welding/ casting so true is true...
i surspect the rubber bushs are used to stop the need to line bore
just jig welded...as the rubber is very forgiveing to misalinement...
by misalinement we are talking points of a millimeter at the eye which would
be millimeters at the other eye...
