hi Hanno,
The original boards on this particular body I have been measuring from are not tongue and groove , but I believe some makers did use T & G on GS bodies .
These GS bodies were built by various companies so I guess some variation in detail is to be expected .
It would be ideal to have a data bank of drawings for various bodies . In many cases civilian owners chopped up the original bodies on their ex WD vehicles as they were not practical e.g. heavy .
I will be adding more drawings as I do them .
Mike
