Rear Window Louvers

[198D13]

Base on louver pins.

As mentioned there are no markings on the aluminum louver itself but hinges on originals do have markings on the underside as seen pictured here.
I was finally able to buy an NOS Cuda louver assembly that I had chased for years...doesn't get more original than that.
Had all the NOS bagged hardware needed as well.
Markings on underside of factory zinc hinges are shown.
First repro louvers had flat backsided hinges, now I believe have hollowed
area but still are distinguishable from original.

Was the Backlight Louver Package available at the start of 1970 production?  I seem to remember that it was introduced sometime into the production year, similar to the FM3 and FJ6 paint colours. But, I could easily be wrong about this.
