H2 wheels with GMC center caps?

[davepl]

Since the 8-lug wheel choice is somewhat limited, of the options available I think I prefer the chrome H2 wheels that I've seen. Those who have used them apparently use a centercap with the Bowtie on them, but I have a GMC (1970 2500 3/4-ton).

So, two questions:

1) Is that centercap I see actually the Hummer one or is it from a Silverado?
2) Is there a good GMC centercap that I can get from a later application that will work?

Thanks!
Dave
