The picture appears to be an MGA 'high mount' starter version. As for the
clutch, how many dowel pins locate the pressure plate to the flywheel? MGA
clutch has 2, MGB clutch has 3. The MGB clutch (stronger) can be used with
the MGA transmission if one also uses the MGB transmission front cover &
MGB throw out fork. Look for the casting number on the front cover. MGB
cover is #22B55. Clutch disc are all the same diameter but the splined
transmission input shaft can be 10 spline (MGA) or 23 spline (late MGA MK2
& all MGB).
