As you can see the whole body should just drop over the cut-down Spitfire.
There should be no major engineering work to do apart from moving the fuel tank, but you'll need a good grinder and a lot of nerve to chop-up the Spitfire body.
I know it's been a long time coming but, we plan on doing some major work on the project next week may-be get it ready for production in July
Here a photo shop mock-up
