A good thread here with some ideas: split bumpers
I think a few here have used the Camaro bumpers. For a Vega they are long and several inches extend over the grille. I prefer to have them stop before the grille like they do for the Camaro. They are not a direct bolt on. I hear that a piece of strap iron works to relocate a hole to bolt them on though.
Some people have sectioned them and then re-chrome. I am not sure if I want to invest in a set of camaro bumpers, cut, weld and re-chrome. That is a size-able investment.
I have heard that two Vega bumpers cut and welded , then re-chromed to make Vega split bumpers. Hard to find one bumper , let alone two.
Here is one done by Vegamods:
Those look VERY nice!
Then you have the cut and flat cap and rechrome. Or cut and leave it. With a nice finished edge it does not look bad:
That is where mine was.
I have added some caps to mine. Not flat , but kind of rounded. I am not sure yet quite what I want it to end up with. These will suffice until I find the final solution.
