Question correct master cylinder for 69 gto

This car had power FDB and the master clylinder is rectangular with one bail. The ads I've seen for replacements show this style for 1970 with the 69 being more oval with 2 transverse bails. My current power booster has the Delco-Moraine stamp towards the passenger side and upside down. Anyone know what was correct for 1969. Thanks

I think that you need a 309 casting that is stamped EA.

Here is an original with the EA stamp. The repo's probably don't have the stamp,but they look good otherwise.
