I think you should have a look to JaPo's book (Ales Janda and Tomas Poruba) on Bf109G-10/U4 , the whole production process for WNF and its factory Diana in Czech Rep is detailled .

I am not specialized in that aircraft , so one could correct me but the "raison d'être" , od Bf 109G-10 is to have currently produced Bf109G airframes with a powelfull engine (DB605D) . There are too many differences between Bf 109K and Bf109G . So not to have to tool new pieces the Bf 109K engine was adapted to a 'standard' Bf 109G airframe .

Each manufacturer manage it is different ways, there were Erla solution, (a square plate on port side) , Mtt one , and WNF/Dianan one .

But I can say that these machines were newly produced ones , no recycling . The repair / recycling process is completelly different . It could be done at factory level but on different lines , or in other specialized centres.
