Yes Peter, first series Betas had a normal length left shaft and a very long right shaft but that changed very early on to equal length ones with an intermediate shaft incorporating the engine mounts we're all familiar with. Current Hawk builders obviously don't need the Beta intermediate shaft assembly, just the outer shafts mated to the Alfa intermediate with spacer adaptor plates to bridge the gaps and cope with the difference PCD's between the Alfa drive flanges and the Beta inner CV joints.
