@joehernandez509 Falcon Acoustics can provide tweeters, mids and rebuild the crossovers. Some cosmetic parts may be available, too. If you cook the woofer, they're toast from what Falcon told me. Falcon can be reached via http://www.falconacoustics.co.uk. They also manufacture new 15 ohm LS3/5A to the original BBC / Rogers specification.
Good luck & happy listening!
