Looking for Lug Nuts

Listers,
 
(Third time trying to send this. Apologies if you've seen it already,
but I have'nt seen it post to the list yet.)
 
At Britfest today I purchased a set of aluminum rims made by Western
Wheel (13"x5.5"), with the oval lug holes. If I remember, they're off of
a Jensen Healey. Anyway, I'm looking for a set of shouldered lug nuts
for them, to fit the stock 3/8 studs. Anyone know of a supplier?
 
Thanks!
