It happened all of a sudden. My gauges quit working and I have no idea why. The only gauges that work are my mph and my amp. Its a 74' 260z. Any help would be greatly appreciated.
I realize that this is an older thread but in case anyone with a 260z comes looking for answers they can find them. The speaker size that fits best is a 5 1/4" You dont need to use the original speaker brackets, you can simply screw in a new speaker using the original screw holes. I would redo all speaker cable though, if you dont it could cost you a blown set. Good luck.
