Hey guys. I've got a really nice 4 door Belvedere, with 29K original miles. The only thing I'm aware of non-original, is a repaint in the 90's. I've been enjoying it for a little while, but I need to do few minor repairs.

1) The generator quit charging. Should I just convert to an alternator, or are there parts available?

2) The heater core started leaking in the floor board. Where can I get a replacement?

3) The horn button is really sloppy and will contact when turning. Haven't taken it apart yet, any easy fixes there?

Thanks!
