I don't know about the early years, but for '99-'02 there is an issue. The painted (non-chrome) bumpers only came on the Limiteds with the fancy flares.If you have a base model or an SR5 like mine, your only choice is to get chrome and repaint it, which is what I did, like the poster above. I used a flap sand wheel on a grinder and went to town on the chrome leaving it nice and dull, then acid etch primer, fillable primer,Duplicolor graphite, clear coat rattle cans to match my wheels. Came out nice.
Please put your year and model in your signature. Saves us a lot of time and you will get better answers.
For new ones, I use Certafit. They have decent quality (not great) for a decent price.
