That is the same bike I am working on now but it is "Stock" meaning it has not been altered. I order to achieve the look and fit for the loop the two top bars are extended 3-6 inches. You would have to determine (measure) where the cuts were made and how much was added, then apply that to the stock foam.

I have been in correspondence with ACME Labs and they are in the process of fabbing me a tank. I made a foam mock tank that their working off of.
