Product Description
This is the metal channel that the side glass mounts into.  The glass track roller guides, in turn, attach to these.  Danchuk # 1011 will work on the front driver side window of any 1955-1957 classic Chevy hardtop or convertible. 
Please note: There were more than one design for some channels; therefore, this channel may not look exactly like those in your particular car, and parts for some models may require minor modification.
