Have a set of arnesons asd6 on a scarab 3 does any one know if they made extension boxes for these drives?

The original bravo conversion set up had asd6 's on them so they might share the same bolt pattern as the asd7's what do the ones you have look like .

Thats what I was thinking, I email arneson and was told they do have boxes available for $2500 a piece

Thank you for the info. Was that price for the inner mounting plates as well?
