While moving my garage and all it's contents to my new house I took a good look at a B18 I've had tucked under my bench for the last 4 yrs, it has an alternator mounting tab cast into the block. Did they make a lot of these? This is the first one I've seen in person, although I've heard mention of it on the board. I'd eventually like use it for something in the future.

I pulled it out of a 66ish 220 that was so rotten the front end was held onto the fire wall with wire mesh and fiberglass.
