Very nice Chris. Well done! If you haven't painted it yet, I think I can help improve your design and lessen the chance, although remote, of bolt sheer if you hit something solid front on. In your second picture you can see a hole in the chassis rail. Welding a tab out over that with a large stubby locating pin welded in to your plate, would provide a lot more mounting strength. You can just see it in this pic.

If you have painted it... then a pic of the finished product please?
