C2 Power steering cylinder differences

[Dave #24235]

My 66 cylinder was replaced by a technician who discarded the old one. How do you tell a 66 from others, or from new ones currently for sale? How do I identify a used/rebuilt cylinder for my 66?

I've never noted any differences in these cylinders. That's supported by the part numbers, too. The part number of the cylinder used for 1963 was GM #5691112. The part number used for 1982 was GM #5691112. All the ones in between were 5691112, too. The one sold today is GM #5691112.

Of course, just because the part number has remained the same doesn't necessarily mean that the part has not changed in some minor way. However, as I say, I've never noted any differences.

Some rebuilt cylinders have the main tube of the cylinder cut and welded. If so, this weld is easily discernable.
