1970 6 lug wheel spacers?

[95gATL]

Have a 1970 c10 with six lugs. Original wheels.
Have a later model mid 2000s chevy 16" alloy wheel/tire combo off a Tahoe / silverado.
Obviously the center axle between old truck and later model trucks is off about 1/4 inch or so. Bought a 3.5 inch hole saw. What a pain. I've decided not to go that route.
Hence wheel spacer idea.
Anyone know exact thickness I need???
1/4"? 3/8"? 1/2"???
I suspect many have done this before.
Thanks again.

PS: also would new lugs and or longer studs be required?

I would use a 1" bolt on wheel spacer like this.
And maybe a 1-1/2" wheels spacer on the rear to help offset the track width differences.

Those are pretty cool.
What kind are they???

Looks like these will work???
Great idea. Thanks so much.

I think you want a spacer with 7/16 thread.
Like these:
Amazon.com: Wheel Adapter 6 Lug 5.5" to 6...
The version you linked are metric,... but will work with metric lug nuts.

Thanks again.
Read the review and someone used them on their older c10 truck.
Perfect!!!

I would mock up the wheels on the truck and measure for spacer width that YOU like.
