71 Nova 3 speed manual transmission - steering column question

Hi, we have a 1971 chevy nova. 3 speed manual transmission. The steering column has a piece that is broken.  We are not sure of the name, but think it's the steering bowl.  It's inside where the shifter arm connects to the steering column.  I have a picture I can send (or is there a way to post on this forum?) Can anyone point us in the right direction to obtain the part?  Thanks
