Bee, your experience is exactly why I tried to find someone to bend a custom one up for me. I figured if I spent the $350 that Isuzu wanted for a stock bumper support that it would eventually just rust out again. At +/-$250 for a custom, end capped and painted bumper support that shouldn't rust out it sounded like a deal to me.
