I'm not familiar with the 250 I run a 292. The spacers Sam refers to are on the passenger side. There is a difference between passenger car mounts and truck mounts that has been discussed. You might want to try and do a search of the forums to see what you come up with. If the local search doesn't work for you can go to google and type in - keywords site:inliners.org and come up with a little more info each results. There were some pics showing the differences. Hope that helps.
