I have a 85 Camaro which came with steel Rally wheels when new. I want to put 84 Z28 aluminum wheels on. Now it has Keystone aluminum wheels with mag style lug nuts with washers. Are the lug studs and lug nuts the same for the Z28 aluminum and steel wheels which were original. I checked with the parts stores and they only show a acorn nut not a capped black one like I want. What do I need to do to make this work. Thanx

 

The studs should be the same for all Thirdgen wheels and cars. Not sure about the lugs.

 

AFAIK all thirdgen stock rims used a tapered seat style lug nuts.
If you want factory style lugnuts w/ a black screw on cap, they're prolly still available from GM.
...ed

edit...had to add that i meant stock thirdgen rims, not thirdgens in general, cuz obviously lug type depends on wheel.

Napa has what you need(probably other stores as well). I got the external threaded nuts and the screw on black caps. Your original wheels might have had some short lugs(plain ones) that were covered by a plastic center cap, if I'm thinking of the right wheels. Those lugs won't work. I saw the results of this on an 83 that swaped on some aluminum wheels. The nuts didn't a long enough taper and the hex part of the nut tore into the tapered part of the wheel.

The z28 wheels do have a deep tapered hole and looks like the lug nuts that were used went to the bottom of the hole. They all use the same thread size and the parts stores I tried showed the same open acorn nut for all models but the taper was about half the length I would need. Im looking for the one piece black ones and I cant afford original GM nuts so I will measure the depth of the taper hole and try Napa and match something up. Thanks for the help.

 

did you try gm? they can really surprise you on some of there stuff it might not be as bad as you suspect

 

A replacement lug nut from GM the style I want are $6 each and I need 20 of them.

 

82Camaro, I had those lug nuts. They looked like a solid closed-ended acorn, but was really just an open-ended acorn with a silver plastic cap over it. I had new tires put on, and the shop cranked the lugs on. I always do a re-torque of the lugnuts.. and found out they were all on there TOO hard! I loosened one, then went to my second. The plastic cap actually stripped off in the lug wrench! I went back and complained like hell... they loosened and re-tightened them all for me, but yeah, those lugnuts are crap.
