everything i've read says, check the numbers on the reverse side of the spindle and you'll see a ford part number.if you see either F4Z8 or F5Z8 then you have 94-95 spindles. The first two digits are the year code. F4= 94 F5 = 95.
or another method is..
checking the spindles is even easier than that.
look at the tie-rod mounting arm on the spindles.
if it's straight or is it curved
curved arms are the 94/95 spindles
straight arms are the 96+ spindles
