yes talked to vw heratige and they have never heard of them , it was vw heratige who suggested Intried asking about my problem here at club 80-90
it seems line boring was more common in europe so you might look over la manche
just had a look on VW catalogue and can't see them so must be aftermarket , if not made by KS maybe by Mahle?
Somebody must have made them in the past as you have a case with some in.
I think vw made them , not sure but on the number 3 bearing, I think its 3 , anyway the bearing that is split into 2 halfs it has VW Ca 025105539 Germany stamped on both halfs on the side that fits into the case.
Bearing number 2 the one that is split in 2 halves has VW Ca 025105539 Germany stamped on the casing side of the bearing on both halves so I presume they were made by vw , bearings 1,3 & 4 have no markings that I can see

number 2 bearing the one that is 2 halfs has VW Ca 025105539 Germany stamped on the casing side of the bearing , but bearings 1,3 & 4 dont seem to have any vissable markings .

Did you have any luck measuring the bearings ?
yes I have measured the bearings and the crank the bearings measure 0.25 u.s as does the crank , but the bearings outer face that sit in the case measures 0.5 bigger than std and the case also measures 0.5 bigger than the std case size .
