Only after I posted this and came back from a junk yard, I found a sticky. Thanks.search IS your friend, READ TE STICKIES!!!!
yes, and yesIt is true that some other cars Like Volvo and Lincolns with fit the bolt pattern. If the offset is not the same or very close it may look funny and cause premature wear on front end components.
something like thatI believe the offset is 42mm for the Taurus/Sable.
it's lug centric and HUB centric. and exactly.Also if the center bore is over sized you will have to take extra care to tighten the lug nuts as you will be going from a bore centric wheel to a lug centric wheel. There are bore spaces that can adjust for any differences but there is no guarantee you can get the size you need.
HERE!!! and READ THE STICKIESThere are some websites that give the specs on many cars I just can't remember them as it has been a while.
Good Luck.
