I know it's not from another H4O member but I bought mine from
CarID for $276 shipped because they price matched a competitor who offered free shipping.
CarID charges $135 shipping for freight to me, but call them and tell them that Jegs offers it for
$264.74 + $99 shipping and see if they will price match it. Worst case scenario if no one is selling their winch mount, you can get it from CarID for roughly $365. Just make sure you specify the one with the winch mount.
Alternatively, you can always browse your local craigslist for an H3 that has that Steelcraft Brush Guard. I've seen it pop up on some H3's for sale in houston several times. You might be able to talk the owner into letting you take their brush guard for a few hundred bucks. They're pretty easy to remove.
Hopefully someone here has one though.
