Bumper Bracket Kit Cost?

I just had the rear bumper brackets all replaced on my 98 Trooper (some had rusted out and bumper was about to fall off). I'm wondering how much these parts cost - I took it to my local (independant) shop and they've always been good to me in the past, but they charged an amount that seems crazy to me for a handful of brackets. Does anybody know what these typically run, I can't find them online anywhere.

see the faq's and call up St. Charles Isuzu for a quote.

Thank you, I did just that, and they were within $50 (assuming all my brackets got replaced, must go look), so I guess thats close enough.
