: Master Cylinder identification please

I've got a master cylinder on my 68 that I'd like to positively ID so I can order the replacement kit before I pull it off this coming weekend.

The cylinder has numbers on the inside bottom that read "Y 5840845" and then there is a little icon that looks like the AC Delco symbol. It it on a car with power drum brakes, and the cap & gasket are correct for a 68 with power drums. It has two reseviors and also has bleeder screws above each outlet line.

What I would like is confirmation that this is the correct MC for this car. I didn't think they had bleeder screws. Then I would need to know the bore size so I can order the correct kit. I've searched for this online and can't find a match, and my Chevy "numbers" book is pretty much only for engine parts.

Thanks
