My dad just purchased a 1969 Ford Galaxie LTD 2 door with a 351w. The car has been in strorage sense 1994 but only has 30,000 miles on it. But to get to the question, on the tag that is in the driverside door jam, under tran for transmition it say's X. I was woundering what the X stood for? Does it mean the FMX tranny, or C6, or C4....? Thanks.
