Are there date codes on bumpers, if so, where will I find them?
No, bumpers aren't date coded, nor are there any part numbers on them.

Is their anyway to tell the difference between original and after market?
Older thread, one of several that popped up when entering "original bumper" in the SEARCH box

I think the date code occasionally popped up on some of them - I had the occasion to help a friend with a 7000 mile original '68 SS car, a survivor that was featured in one of Hooper's books because of the frame markings, original Corvette Bronze paint, and extremely low mileage and originality. To make a long story short, my friend proceeded to re-chrome parts of the trim, including front and rear bumpers and the guards through Advanced Plating in Nashville, with the car stored at my house while waiting for a local (and talented) painter to touch up the car. When we removed the rear (and detached the center bracket from the bumper) it exposed a date stamp (impressed) on the back side of the rear bumper, an April '68 stamping (car was a May or very early June car if I remember correctly). First one I had ever witnessed, and unfortunately before cell phone cameras and even my first digital camera came into being, but it was there. Moral of the story - I should have discouraged him from even touching such a low mileage example, but he was really obsessed with a blemish free car. And he eventually got it - before he sold it. True story -
