I am looking for a set of 4 wheels for my '89 240 wagon. A quick search on ebay shows hundreds of choices, few though specifically for the 240. My question then is, what fits what. Will 740/760 wheels fit? How 'bout Mustang 5 lug? How 'bout Jeep 5 lug Mags? What are my bolt circle/offset specs? Thanx, Jeff
