50th Anniversary Questions

[oneburgerboy]

Hello folks, I'm new to the site and recently bought my first c-10 that I think is a 50th anniversary truck. The truck came with a long bed but when I took it off I noticed the last owner welded brackets for the bed and welded a late model bumper on the truck. After I took the brackets off and grinded the weld clean, I noticed the real color on the back of the cab is a two tone gold and off white. There is no build sheet and the glove box is un ledgable. The sun visors are gold, so is the dash, original cab, clip, steering wheel and fixtures.

The vin is CE148Z15xxxx. This all leads me to my main question which is,could this be a 50th? Did these trucks come in stepsides? Doesn't the 4 in the vin mean stepside?

Thanks
Chris
