I didn't think about this until mounting the wheels. The rear axle, being from a '66 model, had left hand lug studs on the driver's side and nobody makes LH mag wheel lugnuts. I didn't want to take the axles back out to press in new studs so I used a trick I saw my dad use many years ago. Use a 2 lb or so hammer and just kinda let it swing into the lug studs with no real hard whacking. After a few whacks, the stud will pop out. Now here is the trick, put the new studs in the freezer for a few hours. Spray some WD40 into the stud hole on the axle flange, insert the cold stud, and using several washers and a lug nut turned backwards, slowly tighten the nut with a breaker bar or torque wrench. Watch the back side to be certain the stud is going in straight. Use a long prybar jammed between two studs to keep the axle from turning. When the new lug is flush, reposition the prybar and remove the nut.
Screw some lugnuts on the new studs to prevent thread damage from the prybar.
I hope this might be helpful to someone. Bob
