Great. Thank you. I see it now, that piece is like a track for the original unit. It was so odd looking, I just couldn't understand how it was related to the spare tire. Thank you, I think I have an idea of how I'll do it. I'll snap a pic when its in. I think I may try to find a smaller spare though. The 235/75/15 really hangs down pretty low. Darn, I have three spare tires sitting around (all 235/75/15). The other posts I've read on here do not speak highly of that original unit. A lot of people on here have said its more work than its worth and I didn't see any immediately pop up on ebay so I'd have to do some searching. Thanks again
