Saleen centercap help

i've had my chrome saleens for a few years now and want to change out the stock R stupid lookin replica center caps.

I got them from wheelreplicas.

Will these centercaps fit into them?

wheel replicas said the centercaps were 2 1/2" but these from stage3 are listed as 99-04 2 7/16.
