Drive Tunnel Boots

[Tedredamphi]

Does anybody know the exact diameter of the "Drive Tunnels" that the boots fit over? I know that a 4 inch boot fits, but was wondering if a 3-1/2 inch boot might fit? See attached picture!!!

Whatever you use it MUST be resistant to grease and oil and be able to take the heat as well.
