Turn signal issues

[bluegargoyle2k]

I have a 1980 Honda CB900C. Just to get it ready to pass inspection I need to replace the relay. Is it possible to find a relay for another bike that will work in mine without costing me $30+ and 4 days waiting for it to come in. I plan on replacing all lights with more modern and brighter lights later, suggestions are welcomed, just want to get it to pass state inspection for now.
