valve stem hole size

What is the valve stem hole size in ZR1 replicas?

I need to get some bolt-in valve stems and not sure what size to get.

On Summit it has these options,
* 7/16 in.,
* 5/8 in.,
* 5/16 in.

I think I'd guess 5/16??? but not sure..

7/16 is typical. If you're running tubes, 5/8's

We have them in stock if you need them. They are 3.25 each.

The ones we use work for both applications.

I'll be using Mickey Thompson drag radials.

Steve, I'll be calling soon to order that ABS delete kit, so I'll have to add some of those to my order... Thanks
