CJ's used a 5x5.5 bolt apttern, and fords use the same. the only difference may be the centre hole may be bigger on the fords. should not matter really. so you could use the spacers to convert your 5x4.5 TJ to 5x5.5 CJ/ford. remember that the spacers are 1.25" thick. so any aftermarket rims may have a small back space all ready.
