Questions on Dates and other repair & such

Trying to get an idea when some things changed on the M151A2s

When was the Emmision control stuff added.

When was the ROPS installation program started.

When was or??? the 25 amp generator changed to 60 amp alternator. I assume all A2s had alternators but...

Is it hard or are any special tools required to replace the seals on the differentials, or for that matter any of the other cases. I would think it would be easy but just have never done any before.

The emissions stuff was added after 1974 I think. The ROPS was started in the later 70s or early 80s I just can't remember anymore... All A2 came with Altinators.
