i have both high and low horns from my 69, only one barely works but both of them are original and can be refurbished.

A working horn--$40-50
Non-working horn $10-20
Cost to have them restored $200 for a pair.

Boy, if anyone can find 289 and 290 horns even as cores for $20 to $40 a pair, PLEASE tell me where.

Non-working, cosmetically decent 289 and 290 horns (needing cleaned and restored, but with good stampings and not badly corroded or damaged) seem to sell for $100/pair and up.
