A Source for Longer Lug Bolts?

[NJ Oliva II]

Hey guys,

I have a '90 V8 and just received my 20mm H&R wheel spacers (with factory
alloys).  Now I need a lug bolt that has about 20mm more thread so as to
maintain the same "bite."  Any idea on a source?  It's a 14mm ball-seat.

I need to figure this out quickly because if we don't have a President after
Jan. 20, I'm sure the world is going to fall apart.  Also, after Jan. 20,
will Bill Clinton get paid overtime?

Thanks for your help.
