Does anyone know if an 86 GT front bumper cover will fit on my 89?

 

Not without changing the hood and lights.
If youre just replacing a damaged part youll need one from an '87-'93.
If youre converting to a 4 eye setup youll need the hood, lights, etc to do the swap.

 

Thanks

 

You'll also need to change to the '86 and earlier front bumper beam since it holds the turn signals. The wiring is different too, but easy to splice.

Don't forget all the side trim doesn't match, and the fender extension piecesare different.
