Thanks for the pics but I thought the T type ones were different than the Gn wheels ? And the Raybestos obviously was not factory
Not sure what came on the GN. I thought all Turbo Regals came with the same lug nuts. Maybe someone can chime in who has the GN OEM lugs.
I just posted the pics of the Raybestos for comparison purposes. Hope this helps
Thanks. Hopefully someone has them
If I remember correctly, the round(concave) ones were for GN’s. The Raybestos version(convex) are for the Turbo Regals(Non-GN’s).

As for NOS they’re rare as hen’s teeth.If you’re looking for some.

If ya don’t mind aftermarket, you can find them.
those early(84-85) gn wheels and the 86-87 turbine wheels are the same except the gn wheel has the black between the spokes. I know the 86-87 came with the capped flat top ones with metric on the top. the earlier ones might have not sure. the steel gn wheel of the 86-87 came with the capped and rounded top. I'd have to do some digging in the stash for pix of each . not remembering what my 84 ttype had for lug nuts but it did have the more finned aluminum wheel. I like those better but never had another set after I traded off that car.
lots of "better" nuts out there than the original stuff. those caps are just a bad cover up for cheap lug nuts and if you were swapping wheels at the track/street they took a beating.
