I'm quite certain the older ('89-'92) LX centercaps will not fit the XR7 rims. They are larger in diameter. I do not know about the LX fan wheels ('93-'95). I think they changed the centercap diameter in '93 so the LX and SC rims used the same size. I am guessing that the older SC wheels also used the 6-1/2" diameter cap. Other wheels with that size cap are the 91 XR7 (same as 89-90 style), '92 XR7's with the 16" rims (pretty rare, I've only seen a couple of cars with these rims), and the 96/97 XR7's with the sport package (used same style rims as '89-'91 XR7's). I know where to get the 6-1/2" Cougar centercaps brand new for a very good price. E-mail me for more info. (varn8030@hotmail.com)
