Do you have to loosen the intake manifold or oil pan for clearance
when reinstalling the chain cover?  '74 W-200. Getting the chain cover
back on it's a really tight fit. Smears the gaskets out of place. If
you loosen the pan, won't that muck up the gasket all the way to the
back? First offense on this procedure. Been lucky for hundreds of
thousands of miles on several rides.
