[terramir]

Hi guys this is my very first post, I got an 1986 2.3L(I think or was it 2.4 hmm) 1986 mustang LX, well it runs alright except for when it's cold(stall city got to get the engine rebuilt hehe) but my question is about the original rims and tires for this model because I got R14 on this one I looked on one site and it said I was supposed to have R15, can anyone point me to a decent site where I can find real mustang parts?
well maybe used ones I dunno
