1985 Dually Aftermarket Lug Nuts ?? Can't find correct Conical seat angle..

[hotsam]

Like the title says... I'm running stock 16" wheels and Lug Rings on my 1985 3+3. Parts manual says the stock Lug nuts are 90 degree conical seat, as are the stock replacement nuts you get from the parts store. I'd like to run some tall (2") or so chrome or billet nuts on my truck but so far have only found a 60 degree seat advertised that say "will not fit stock wheels". Now I've probably mix matched these seats many times un-knowingly on my many junk vehicles through the years but I pull a lot of weight with this truck and want it right. Anyone have a solution other than stock Lug nuts ?? Thanks in advance
