Hopefully this works. Near as I can tell I can not post a file for download so I have scanned in the images and posted them as a jpeg instead.I have included a legend bar to show the scale of the drawings as well (the bar marked as 5cm).
I do not have any templates for the body itself, but I can tell you that I extended the main body by about 2 inches. This portion was done on the fly and completed before I thought to keep a record of what I did to convert it.
Hopefully these are helpful to whomever wishes to use them. I want to say I would appreciate a mention that these came from this blog (i.e. mine) but considering I am copying a design conceived of by someone else, it would make more sense to say "Have at it".
