Could someone please tell me the size of the hub centers on both H1 stock wheels and H2 stock wheels?!

I have searched online and every website I look at has a different size for the H2's.

I'm looking to buy some spacers to possibly interchange military H1 wheels but still have the possibility of using my H2 stockers. However the spacers I've found are hubcentric so I need to make sure the diameter will work with the spacers. I'd much rather have hubcentric than lugcentric spacers.

Thanks in advance!
