Hello everyone My question is that is there any way I can download a livery for the PMDG 737-800 then stretch it out and use it on the 737-900 by using livery tools or any other method? For example would I be able to download a 737-800 then put it in a software make it bigger and then rename it for the 737-900? Some liveries I want to use are only made for the 737-800 and I'm buying the 900. Thanks in advance for any help.
