    5 Lug Conversion Question

    Does anybody know if rear axles out of a 99 ranger w/ the 7.5" rearend would work to do a 5 lug swap on my 85 mustang gt? My 85 has the 8.8" rear. I read that two driver side axles out of earlier rangers would work but I'm not sure about these. If anyone knows if the 7.5" or 8.8" axles out of a 99 ranger would work i would appreciate the advice.
    Thanks

    To convert the rear end to 5-lugs you need to replace the 4-lug axles and drums with 5-lug units. The axles that are needed will be either off of a Ranger, Bronco II or Aerostar van. From an '83 to '92 4 cylinder or 3.0L V6 Ranger/Bronco II with a 7.5" rear end you will need two driver's side axles. Only the driver's side will work as the pumpkin on these rear ends is offset and the axles are different lengths (you need the longer of the two axles). It should measure 29-5/32".

    From an Aerostar you will need two of the passenger side axles from an 86 to 97 model. The axles are all the same so they can be mix-matched (i.e. - one driver's side axle from a Ranger and one passenger side axle from an Aerostar). You can use the brake drums from either side of the above listed vehicles but make sure that they are 9" drums. The 4.0L Rangers came with an 8.8" rear end with 10" drums - these will not work.
