Yes, I'm sorry I should have said AM or AM/FM. U63 and U69 both had the front center speaker. If the stereo tape player U57 or the stereo multiplex U79 was ordered, no front center speaker was installed. My apologies, I sometimes forget the U69 FM non-stereo option, which was actually fairly common. I only had an AM radio. Also AM radio is evidenced by a rear telescoping manual antenna, the rear antenna option could not be ordered with the FM radio. I believe AM and FM both had the same straps and capacitors, but I could be mistaken. I'm sure its all in the AIM. The original rear antenna on my car, and the original AM radio still installed, is how I knew the rear spoiler was added. It was an original rear spoiler, but it could have been added by the dealer or from another car at any time after the factory.
