The speaker in our dash was in pretty bad shape, so we went to our local Radio Shack and purchased a replacement (Cat No. 40-1297c). The "cheese cloth" that covered the speaker needed replacing. This was purchased at an upholstery shop. This speaker is almost a direct bolt-in, with "almost" meaning that the only change we needed to make was to reinstall the bracket for the speaker upside-down and use machine screws to attach the speaker to the bracket. The speaker can then be bolted back in its original location.
