Wiper switches?

[eighteenninetytwo]

Were there any differences between wiper switches in 75 thorugh to about 86?? i replaced mine with one from the pick n pull form a pickup. I didn't check that it was identically aligned as it fitted fine. The Dash Bezel doesn't go back on now apparently (says the Auto Audio guy who is fitting the radio).

Alternatively is it the bezel - it's a new ( to me) Bezel from a '73 with A/C whereas mine was a '75 with A/C - did that change at all - it looked identical to all intents and purposes when i got it.
