Left and right nose gear door part numbers
 

Does anyone know if the same part number nose gear doors were used through-out the 337 production run? Asking as I am shopping around for a used right side nose gear door for my 337D and found two part numbers for the right door on ads online. So when did the doors change -- or is there possibly a typo in the part number in the ad?

My parts manual only goes through 1969.

In the parts manual you can see the two part #'s
At the bottom of the page you can see the serial #'s they are used on
Looks like one is use on the non tubo and the other is for the turbo model
I have attached page from parts manual for C-337 65 thru 69 models
A 337D is a 1969 Model

Thank you Frank!
