Re: searching for a bumper...
I think I saw tha bumper at Fly-N-Hi here in Arizona. They are pretty much a local shop but they do mailorder business nationawide. They have their own fab shop that builds the Pre-runner style bumpers(and a whole bunch of other stuff). They do so many custom bumpers that probably no two look alike.
Check out http://www.fly-n-hi.com/tj_feature.html
for more info and a pic to something similar. The Pre-runner style bumpers are pretty popular here in Az.
