Bumper Surgery
#13
If it were me, I'd probably take my time pre-scoring it heavily with a utility knife and then hacking it off with a sawzall that had a fine tooth metal cutting blade. I have cut through vehicle plastic using a cutoff wheel on a dremel and although it works, it tends to melt the plastic and make a mess.
Lastly, I might try a quick wisping of the edge with a torch to then smooth out your grinding lines. I would practice this on the cut-off piece first to see how it goes.
Oh, I would do all of this with the bumper off of the vehicle.

Ok ive been thinkin about this a bit. I agree no power tools. First I wouldn't cut it right to the crush can line. I would probably go an inch off of the crush can. Then use masking tape to get the right line, then score the line with a utility knife, then use a hack saw (the small kind that just hold one end of the blade), then sand with a fine grit, then to top it off I think I would find a material like what they use for jeep door edge guard which can be glued and press fit over the cut to form an almost factory job.

Ok I learned three more things. On the front bumper if you cut within 8" or so of the crush can you also have to cut through a psuedo steel bumper. If you cut only 10" or so off each side you will cut just plastic. (not an issue on rear bumper its all plastic, but would have to remove bolted on metal supports)Also, I have a feelin the blow mold bumper is hollow, meaning if you cut it you will have what would look similiar to a slice of an empty calzone. Lastly, The plastic remaining will be approximately .5" thick so my idea of using door edge molding will not work but something similiar of a thicker degree would and cover the empty space inside the bumper.

I think the peiece you are referring to is a tough ABS plastic. Not even aluminum that thick would flex when you pushed against the end of it. I pulled my air dam off today, and started looking at the possibility of stubbifying the stock bumper.
