hummer wheels on '79

[jimmmie '79 Cheyenne]

I know the bolt pattern is the same for all 8 lugs (8 on 6.5) , but '88 to '04 and maybe current takes a 14X1.50 lug nut vs the 9/16 on pre '88. Will my lug nuts seat correctly on the newer wheels or do I need to do s o m e t h i n g .... Went out when I bought the truck and put 8 X 16.5's on it, not knowing at the time 16" was really better. Dummy me, but that was long ago in the last millinium, Jan of '79. Any idea what take-offs are going for on the newer trucks? thanks...jim
