Yes, there are two types of camshafts. IMS, the break points are at the
1296 - 1493 engines. I know that the 1500 has no cam bearings, but ISTR
that the late '70 1300 that is currently in my Spit does have bearings.
Most of the catalogs have given a breakdown, but I will check my factory
manual and see if the break is given there.
