Getting ready to buy some chevy tails off my friend but we can't get the top bulb to go in. One of the notches on the bulb cassing is too big. I thaught all these types of tail lights would fit.

 

what years?

 

I got it. My truck is an 04 sierra. The chevy lights are supposed to be 05. I had to carve out the tope hole in the light to make one of the notches on the plastic piece that holds the bulb fit. Just took a few minutes.

 

You can also get the chevy harness. They are pretty cheap and the plug in under the bumper in the same place as your.
