If they were never available new from Chevrolet and Jim Carter took the time to make one to have available for his customers to be safer driving in modern times, why would he make it a single lamp???

The above is what I don't get either.
Carter has
1. Separate left and right light for 34-39
2. A right tail light bracket for 34-36 (he says "rare" which connotes original)
3. A left license-low tail light bracket for 34-36
4. A left license-high tail light bracket for 37-39
5. A right tail light bracket for 37-39. This note added to description: "In 1937-38, the factory did not offer a right tail light. Few vehicles on the road had them, They were a dealer installed accessory!".....is it a typo to leave off 1939 or does it mean 1939 had this bracket from the factory?
