Tail light plugs (new to this) (3 Viewers)

[gabewelker]

Greetings,
I just picked up a 1977 FJ40, my first into the vintage world.

My tail lights are badly corroded and I can't get them cleaned up to the point of having all 3 bulbs working. I want to replace them, however I see lots of rounded plug versions for sale. My plugs appear to be square. Where can you find replacements with that plug?

A picture or two of the plug(s) you're dealing with would help.
