Other then the wiring...

Will the tail light setup from an 83/84 T/A bolt in along with the center key hole pannel to a 89 firebird?

I like the looks of the early style tailights and my 89 needs a new lens anyways...

Thanks

 

Yep. Direct physical bolt-in. Wiring & bulbs are a different thing, but you already knew that.

 

I've had 89 firebird tail lights in my 82 there was something different about the tumbler for the key thats different and with 89 tail lights in the car made it hard to use the key to unlock the trunk. I think the 89 tumbler is a bit longer then a 82-84.

 

The wiring i think i have under control using a trailer adapter...
So the wiring should be a big deal..

Are the sockets the same or do i need the sockets from the early car? Do they clip in to the back of the lense?
