i am going to assume it has the same measurements and that it's gonna be the 50mm diameter/90mm long can, as the name stays the same... i noticed all of their motors are named according to diameter size first, followed by the length - (BLS-5090) which is a great way to do it imo =)

Do you know what bolt pattern it has? If it's a 50mm can, i can only assume you will need some sort of adaptor to mount her up... and if it's 90 mm long - i'm not sure you will have the room... have you checked the length? i think from memory there is only room for a can 80mm in length? correct me if i'm wrong tho!!
