I used
Flint Bumper Mart (Flint Mi) for my 47 GMC front bumper. Cost me $400 out the door. I'm thrilled with the results. I decided to rechrome instead of replace because the 47 is unique and not reproduced. Easily identifiable by the three bolts on the outside ends. I put a repop on the back for $150.
I sent the grill to
Custom Plating Specialist. Spent a fortune on it, but couldn't be happier.
