Unilug wheels ?

"Dual pattern" is not actually the same as "uni-lug".

I have those dual pattern turbines on my 1980 D-100.

They're fine.

I think they are factory, or at least dealer installed.
Agree, my semantics are faulty. I made mine dual pattern, not unilug. Thanks for clarification. I did have a set of unilug slots. Never a problem with them, either.
