For the 1992 Lebaron Convertable: In-dash speakers are 3 1/2 inches, door speakers are 5 1/4 inches, and the rear seat side panel speakers are 5 1/4 inches. [I found this information on the Crutchfield web site when I was preparing to replace the speakers in my Lebaron. Worth noting, the site also provides a list of car audio components that fit based on your make, model, year and (where appropriate) car type.]

Dash speakers are 3 1/2 inches. They are a real pain to replace. You need to remove all lower portions of the dash.
