One possible reason for different part numbers for the rear hubs (racing/road), is that the aluminium racing calipers had a different hole spacing compared to the cast iron road calipers and as AC only seemed to thread one set of holes in the hubs they would have needed to differentiate.
   You'll probably find that the front steering arms have different numbers (racing/road) for the same reason.
   I agree with Trevor, the Frua rear hubs are different to Mk3 Cobras. The bearing position is further outboard relative to the wishbone pick up points thus making the track wider without loading the bearings.

Where on the chassis is the chassis number stamped or is it like other 428's I've looked at and  the number is only stamped on the chassis plate on the bulkhead?

Peter, if you require RBJ-205's contact Hawkcars, Gerry keeps these on the shelf along with all the other bits that wear.
   As for the Kirkhams, some of the early cars had simular bearings but were metric,later ones use trailing arms like MK4's with a rosejoint at each end.  Later still Kirkhams have billet machined aluminium wishbones and links.
