Thank you for your help, and sorry I never got a chance to take a photo. I ended up finding in the microfiche that there is in fact an oil plug located here. Of course it is no longer available. Luckily I searched the NYC street where I had it parked and found it on the edge of the gutter! So once the gasket comes in (still available) I should be up and running. I have another conundrum but will post with a new thread.
Thanks again,
Michael
