New horn relay hard to find?

[Dibbons]

My four pin 72 SSP horn relay is falling apart. Quick internet search found nothing at common auto parts stores. Is this common item hard to find? Can I use one without the key buzzer? Thank you.

A relay is a relay. If you're not worried about originality, just install a standard relay switch for $5 or so. If originality is an issue, you can get an OEM relay for $45+ on ebay.
