Just curious... does anyone know when exactly the factory changed from the bolt down crankcase to the rubber mounted one please. Is there a chassis or engine number reference?
On top of that, I see that the earlier rubber mounted cases had the feet drilled at 1/2" whilst later ones are drilled at 5/8ths" - I guess that's where the anomaly comes in relative to the centre rubbers. Would this coincide with the introduction of the "low frame" crankcases or was it earlier?
