H3 Wheels on a 87 GMC V1500 4x4 HELP??!?!?

[NastyBuzzard]

So I need some new wheels for my 87 GMC V1500 single cab long bed. I am currently doing a LS swap.

I have been eyeballing some H3 wheels for it b/c for some reason I love how they look. Unfortunately I am not a part of the 8 lug club yet so I have to get 6 lug.

I found some and talked the guy down to $300 shipped.

I have researched and the lug pattern is the same 6x5.5 and they have a 4" hub bore versus my 87's 3.5" I think. So I may need a hub spacer.

What I am concerned about is I think they use a different size wheel stud. I read somewhere about newer trucks being M14 or something and the H3s are M12 or something like that.

Any ideas what I would need to do to get these to fit? Also I havn't found anyone who has pics of this done before.

HELP?!!?

Here are some pics the guy sent me.
