Be sure and tell them which one you need - there is another vacuum pot with a "nipple" on the port that accepts a push on hose.

Assuming you need the vacuum advance chamber with the crooked arm, then the vacuum chamber from a ’58 or later 352 or 390 should also work as well as the chambers for the small block Ford (221/260/289).  The spring tension in the chambers may not be exactly the same thereby making for a slightly different vacuum advance curve but that isn’t expected to be a show stopper on a Y.  But nothing guarantees the replacement vacuum chambers being the same in spring tension anyhow as they tend to be pretty generic to fit a wide application of vehicles.  Just be sure to carry your old one with you to the parts store to insure that you are getting a chamber that physically looks the same.
