I just got this horn on ebay for $24.99 plus $9 shipping. Was wondering if anyone has used it. To me it looks just like the Stabel. Audio clips sound the same from what I can find. Autozone sales the black 419 for &39.95 + tax. They offered to order the crome 519 for $72 including tax. I did the AutoZone aircleaner mod and was looking for something to fill the gap under the filter area.
