Wtb: rival shifter

I am building up my cross bike and finding I’m missing some parts.
If someone has an old rival shifter around, I need the clamp which holds the shifter on the bar.
I’ll buy the whole shifter if you want, or if you are feeling extra generous, you could give me the clamp for a week until I could replace it with a brand new one


I guess I’m feeling generous- just mind my bar tape.
