Front wheel bearings for Lola 642 FF

Does anyone know what the bearings are in the front of a 1983 Lola 642 Formula Ford?



The only numbers I can find are on the plastic ball carrier - F 88.SMPI.2



It's a single outer with 2 ball races like from a front drive car.



ID 30mm, OD 60mm width 37mm.



I assume Lola would have used a relatively common (for 1983) bearing off a production car.



Thanks
