Here are a few I have. In the first picture:

- Top Left is the acorn style used prior to 1970. This particular one is a 60lb unit for a 1966 Olds 442.

- Top Middle is a correct 6462137 dated for my 71 TA.

- Top Right is an NOS 6460032. I have seen these be used in place of the 2137 as they are 80lb units and have the same 1/8" NPT fitting.

- Bottom Left is for a 71-72 Buick, note the 1/4" NPT fitting. This is a 60lb unit.

- Bottom Middle and Right are again 80lb units with the 1/8" NPT, but the number is 6461967 on both. I believe these were used for testing as they still look pretty new but appear to have been used a bit. They are both stamped "DUAL", one with ink and the other stamped in the housing itself. Not sure what the means.
