<VV> Concentric wheel spacer necessary?

[Joel McGregor]

Big trucks use either hub centered or stud centered on disk wheels but not both.  They carry a lot of weight so I'm guessing that using normal Corvair studs and tapered seats is more than good enough.
When I bought my '64 Spyder I ran it pretty had before really looking it over and it had a nut missing on a rear wheel.  3 held it together fine so I'm thinking 4 is plenty.
