Splined Hubs

Option 1"All MGB GTs and MGB roadsters built from 1966/7 were fitted with the Salisbury rear axle. To verify what type of axle is fitted to your MGB (axles are sometimes changed) look at the differential housing. If there is a cover that is bolted on then it's a Salisbury axle; if there are no bolts at the rear but a series of nuts at the front of the differential then the axle is the earlier Banjo type." (Source : 'Enjoying MG' June 2012 p.35)
