Ahh. Ok. I think the switch in the Contours was in 99 (as I just spent about an hour looking for different engine pay pics!). It looks like, in 99 the piece was changed to be just straight across (anyone wanna verify, in case I looked at the pics wrong?). I guess that sleeve-nut can be tightened all the way down the bolt so it'll sit flush.
The only reason I was curious is because I talked to Warren Kurtz a while ago about making some tie downs and he mentioned that there were two types used on the Contour and he didn't think they were compatible. I guess he didn't have the sleeve-nut idea.
I'm very tentative to buy one. Gotta pay my bills at the beginning of this week, then I'll see how much money I have sitting around.
