Always informative and to point......MYTH BUSTER
Some clarity needs to be made on the myth on Aisin hub, 8mm spacer, and stock birfs need to made. Using a 8mm spacer will NOT let Aisin hubs work in place of a needed 2nd groove. By using a 8mm spacer the factory needed snap ring on the end of the stock birf WILL come in contact with the Aisin hub face and NOT work.
A 8mm Spacer will work and are included when you buy POS AVM hubs for an 80 or 100 series.
