The Matador cross member will not fit the smaller cars, it has to come from a Gremlin, Hornet, Concord or Spirit V8 car. If you find one make sure you get the engine motor mount plates too. Check the site below, Galvin's has repo engine plates and has an exchange on V8 cross members, you send them your 6 cyl one and they send you back a 6 cyl one that has been converted into a V8 one. The 6 & 8 cyl cross members are the same it's just the motor mount stands that are different. "Doc"
