On my 1974 1.8 has these plates on the cross member mounts. Are they jack points? I do not see them in the parts diagrams.

Nope. Those look like the big washers that are supposed to be used on the transmission ears so the transmission bolts don't slide out of the mounts.
Btw., there was a thread here last week explaining why *not* to use the engine bar to jack up your car. Or the transmission for that matter ...
