Taillight Curious

[LarryPreston]

I have a 1973 3345 2bbl 727 auto Scout II that I am restoring. I had to get another tub and it was a 1980.
I got the 1978-1980 plastic taillight housing, lens and sockets but I need to know is there anything else I need to get?

The wiring harness is different too. Get that if you can, makes for a cleaner install. Did that on my '74 Scout.
