Why buy new when you can restore?
Yep. When I was looking for parts for a possible truck (a 2500; I was researching the difference between the 2500 and the HD), the HD had the tall bumper cap to make up the difference in frame height (that affected the cab height). And the difference in the grill is the thicker and different style chrome cross-bar.
I totally forgot about the HD hood swap! That was on the '01-02 trucks only, right? I don't think the "HD" came out until '01 when the GMT400 production ended.
DO IT!!! All you swap is the hood (lights and grill are the same).
And I agree with Kyle on PTM-ing the entire mirror, not just the cap.
You are correct on the part about the HD front end only being on the 01-02 trucks. You are also correct about the lights being the same. The bumper and lower valance is also the same. The grill and upper bumper cap however is NOT the same. The pic Kyle posted is not a true HD truck, just a 1500 with an HD hood(or else a regualr 2500 but not a 2500HD) Here is a pic of an actual 01 2500 HD for reference. The HD hood will fit a 1500 truck and lines up with the 1500 grill.
