Are the Sierra and the Sierra HD frontends the same? Same bumper, airdam, bumper cap? A friend of mine is lookin for an all chrome(no airdam or bumper cap) GMC front bumper for his '91 Caddy clipped 1500. Thankd fellas!

 

more specifics please... 03-04????

 

01-02, I have looked around and it appears to be just different mounts and bumper cap.

 

I think the HD has a different bumper. If you look closely, the HD has two big opening on the chrome part on each side of the license plate

 

I think there is a regular bumper and then a diesel bumper. The diesel one has the two holes in it like black yukon said.

 

Thats prob. it!!
