Any help would be great appreciated.

UV maps don't line up. Blame the modder, adjust or figure out a way to get the model to a 3d software and paint the lines there.

I found the solution: Try to fix every line individually. I had to make very slight (per pixel) adjustments per line and add extra infill when needed (my side decals had issues as well). Hope this helps.

yeah, making skins is a lot of trial and error, it's why i tend to keep mine pretty simple
