What sprocket for 1970 Rupp Roadster

#1
I broke a tooth on the jackshaft. I braced a crow bar on the sprocket to remove the bolt on the other side to paint the frame. The bolt didn't budge and a tooth on the sprocket snapped off. :hammer: I had to cut off the bolt with a grinder and now I need a new jackshaft and a sprocket. I know the jackshaft has the pin on one side but I don't know which sprocket to get.

Anyone know?

Thanks in advance for your help!!
