SO where does it say the grill shell is aluminum?
It doesn't, but it doesn't say it is plastic either. I did not look at their website first as I found the grill on another suppliers site. In looking at those sites NONE that I found said it was plastic, most said it was aluminum or steel.

Can you see why I thought it wasn't plastic? The thing is the suppliers do not normally make up their own descriptions as the manufactures in general give them part descriptions. Why the do not change them when they KNOW of an error in inexcusable. I told Auto parts warehouse 3 times, to 3 different people, they were falsely describing the item and they said they would change it. Still up on their site today. Street scene was alerted to the misboxed item and THEY didn't bother to check it out or correct it, just blindly sent another one with the same problem. Again, inexcusable.
Bottom line is I just bought a new plastic grille off Ebay for $103.76 shipped to my door. Had to buy an emblem for it ($43.00) so the total was less than $150.00. The grill I have now was made in the same Taiwan mold as the Street scene version was and I assume chromed at the same place. So you basically are paying over $200.00 for 4 pieces of chromed aluminum flatstock with holes punched in it. I decided to pass.
Have it on the truck now and fit fine so to help anyone else out there, 4500 and 5500 grilles are indeed the same as the smaller trucks of the same year.
Where does it say aluminum grill shell on this page?
Started comparison shopping till I found Summit had the lowest price with the free shipping. Again it doesn't say plastic either.
I'm afraid you will not find an aluminum shell that has been chrome plated, and would suggest keeping the one they shipped you. It should fit and will last until the chrome gets rock chipped, or starts releasing from the plastic, just as your factory one has done. It's likely not going to happen within a few months, but it depend on the conditions you expose it to. Sorry there isn't a better answer....
