Unable to find files

So I've been looking into swapping engines and read the whole tutorial and I seem to have a problem, I cannot find the file.
So i'm hoping to swap the LeGran engine into something but when I go into the vehicles folder there is no LeGran folder (there are only a few official vehicle folders like fullsize and midsize and when I click on them it only shows modded files). The only one I can find is in the cache.0.10.0.1 folder but that doesn't have any of the information the tutorial says I need, I've verified all game files and the car works perfectly fine in game except that there I had an issue a few days ago where there were two LeGrans in the vehicle selector which both worked fine. I've removed I think all LeGran mods and will remove all mods if necessary (I have over 300 mods though so that would suck) but was just wondering if anyone else has experienced this? I can provide screenshots if you want

I was using OS (C > Users > Joe > Documents > BeamNG.Drive > vehicles but I do have the steam version so I'm gonna try and use the one you suggested
