I am pretty sure that 06 are the same as 07, 08. They accept the same modules. they look alittle different due to the 07's not being machined out at the bottom. I am not sure why they did that. I do not think that you would have to change your string length or anything. If you have any doubt call Bowtech customer service. They usually can tell you.
