[DeTomaso] I need some help with parts!

[Garth Rodericks]

Go with 66 Mustang Rotors.  But first read the following past posts I saved on the subject...

  There are a couple of issues with trying the direct swap.  First, the Mustang rotors have 1/2 inch studs whereas your original wheels are built for 12 mm studs.  Larger studs will slide through the wheel holes, but the way the nuts seat may not be as good.  And you are out of luck if you want to keep your DeTomaso emblem lug nuts.
   
  Second is that the hub of the Mustang rotors may not fit into the center opening of the original Campy wheels.  Depending on rotor vendor, the outer bearing hub is slightly larger than the DeTomaso original part.  I guess one could have it machined down 0.100" or thereabouts.
   
  I can't confirm whether the bearings are same size as original, and whether the distance between the inner/outer bearings is the same as original.  
   
  Only the 1965-67 Mustang rotors are even close.  1968 and up use a thicker rotor.

  You'll want to keep the stock studs as they have to fit into the Pantera hubs. This will require 17 mm holes through the rotor as the studs are that much thicker closer to their head. The Campy wheels will fit as they fit onto the Pantera hub, not the rotor. The rotor is installed from the back side of the hub and never contacts the wheel side. I have stock rotors that I can take measurements off if anyone has a Mustang rotor around for comparison.

  The Pantera uses the standard Ford bolt pattern, but it is equipped with metric studs (12mm).  If you put Mustang rotors on the car, you should probably knock the studs out of the old rotor and install them on the new one, if possible.

  The swap was straight forward, they even use the same bearings and seals.  The only two catches are you have to slightly modify a pair of $10  dust caps from the "Help" rack located in about any auto parts store, and then  there is the studs.  The shank on the Mustang stud is ever so slightly  larger than the 
  Pantera shank, so if you put the Pantera stud in the Mustang  hole, it would not "bite" enough to keep from spinning while tightening the lug  nuts.  Before I bought the rotors I did purchase a junk 66 Mustang rotor to verify all of the dimensions, bearing spacing, bearing location to rotor center, etc.  I even bought a tap and resized one of the mustang studs to Pantera metric, and they cleaned up just fine!  However, people who know rotors and studs very well told me this is a no-no since this can upset the correct radius at the stud base, causing the stud to shear off.  I thought it was a better idea to just by inch lug nuts (that fit just fine) than to test the "Lets see if the wheels come off at speed" theory.  I have posted two pictures, one with the rotor on only (http://members.aol.com/parapantera/newrotor.jpg),  and one after mounting the caliper (http://members.aol.com/parapantera/newrotorcal.jpg) .
