Good point. I'm getting the picture.

Interesting. I 'borrowed' one of these caps from a truck at work last year
(the chrome ones) and found that the 8 lug cap had metric spacing and didn't
fit.

Like you, I felt that this smaller center 'cap and a chrome trim ring was a
nice alternative to the more expensive Alcoa solution.

Did I miss something ?

Mark,

The hubcaps I'm trying to use are the 9.5 inch diameter black ABS
plastic ones that GM uses on its late model pickups, not the chromed
plastic ones which usually come with the optional alloy wheels.

The lug nut stud spacings (pattern) for these black ones appear to fit
close to perfectly the lug nut pattern of the OEM GMC MH wheel. The
problem is that the lugs nuts used by GM to mount these hubcaps and late
model pickup wheels are a totally different design from the GMC MH OEM
lug nuts and cannot be used to mount the GMC MH wheel.

So, that's why I'm still looking for a lug nut with duplicate design of
the GMC MH OEM lug nut, execpt that it would be about a 1/4 inch taller
than the OEM (i.e. about 1 1/8 inch tall). BTW, Paul, are any of those
links likely a source for lug nuts?

I hope this search for differnt lug nuts doesn't sound too nutty. If
sucessful in this quest, I should be able to come up with an attractive
alterantive to the aluminum OEM wheel covers (other than the those
beautiful Alcoas) and still be able to display the "GMC" logo on the
wheel.
