Modern Chevy Alum wheels on a '67

[RichardJ]

My '67 3/4 is going to be needing new tires in the not to distant future. It has the 16.5, big/little, slotted aluminum wheels that were popular in the '70s.
I really don't care for most of the new aftermarket 8 lug wheels and I hate wheels with the fake rivets and bolt heads sticking out.

I do like the wheels that are on there now, but the rear rims don't have a safety bead and the 16.5 tires are beginning to fade into history.

I like these wheels but I am concerned about the fit. They are 2007-2010, 2500 and 3500 and still have the 6.5" bolt pattern.
I can get around the 14mm-1.5 lugs a couple of different ways.

The guy I buy my tires from thinks the new GM truck wheels have too much positive offset to work on my '67. He thinks the wheel/tire will be moved too far inboard and reduce the treadwidth. He isn't sure if there would be any interference with the '76 disc brakes and steering arms.

Does anyone know the backspacing on the new GM 8 lug wheels? I've been looking around the internet, but can't find any thing.

Has anyone seen these or any of the new 8 lug Alum Gm wheels on a 67-72 truck?
