JC Whitney does sell 2 models, one with the wrap around light guards and one without. They also come in black or chrome.
I have found a cool on eBay that there is a company that makes them and they look tough, however I can't seem to find them on eBay anymore and have not seen them for some time now.
Honestly, I have always wanted one like the company down in Texas makes called Ranchhand bumpers, and get their Bull Bar bumper, but they don't make one for our vintage trucks. I even contacted them and a few other companies down in Texas about making one for our trucks, but they don't want to custom make anything and i was bummed out about that.
