The last one I replaced came from the dealer. The customer had ordered a pattern part with stubs on it and, after I cut the old one off, we found that it didn't quite fit. He ended up getting a genuine part but it did not have the stubs. I spent a lot of quality time under that Defender recreating those two sections of the chassis. This was 3 or so years ago, so I'm not sure of pricing, but I seem to remember it being closer to $500ish that he paid for the part. That being said, if you opt for an aftermarket part, take lots of measurements before you start cutting ;>) The moment I realized that the new part didn't fit is not a moment I care to relive...I think I wanted a cigarette really bad...and I don't smoke. It all worked out fine, but telling someone that you cut their truck in half and now their parts don't fit is very hard to do.
