55.2-59 56 gmc grill differences

[Phungki]

So I recently bought a 56 GMC. St least that’s what the tag says anyway but the front end is different than what I see on other 56 GMC trucks. First off my grill more resembles a Chevy. It’s not the big mustache looking grill you see othe GMCs with. Secondly My hood doesn’t have the indent where the GMC emblem sets. Why the difference? Or is mine some pieced together homemade hybrid!
I’ll post a pic of my front end and a pic of one I pulled off the web so you can better understand what I’m talking about.
