The original is a squarish speaker (maybe 6x8) and VERY shallow. The standard 6x9 won't fit, if I remember; been awhile... Also, the speakers are 10 ohm and NOT the current 4 ohm that is used today. Matt Nall Charleston, Oregon http://tinyurl.com/The-Corvair-Patio http://tinyurl.com/Matts-Tech-Pages
