rather than create a new thread, I am going to ask a question here.
Are 1970 Firebird (and Camaro) front speakers esthetically a one-year part too?
To keep this simple;
1) I recently looked into this and noticed that my MPC lists the 1970 speaker as different than the 1971+ speaker;
Grp 9.50 SPEAKER ASSEMBLY FRONT (nov 1974 printing date)
1 - 7311432 1969-70/ALL - LESS BRACKET
1 - 7932772 1971-74/ALL - 4 IN X 10 IN
This is a speaker that is known to have come from a 1970 Trans Am:
This is a speaker that I am not quite sure where I got it, but it needs to be rebuilt:
You can differentiate the first two speakers in two ways (so that you don't think I am showing two different pictures of the same speaker);
1) the stamp on the magnet is oriented 180 degrees from the wire pad(?)
2) this second one has the green positive cable missing
This one is a speaker I probably got from a 1970's Camaro - note that is a completely different shape from the other two "1970" speakers - but it retains the same shaped magnet, and uses the same bracket to hold it up in place.
(
if anyone knows how to clean the tarry mess that is from the surround, I am all ears;
The earlier speakers appear to have a glued in place styrofoam surround, while this has a tar strip (like a period window seal) that has been leeching when it gets warm.)
Please notice that all three speakers have the exact same stamped part number on them 7314362.
Now, to throw a curve ball, that MPC listing suggests that 1969-70 speakers are the same, which I find confusing, but when I do an online search for speakers, it looks like 1969 Camaro/Firebird speakers use a dedicated ground wire, while these ones I have here are all grounded speakers.
Thoughts??
