Well I guess I'm gonna email GAZ about my case then and hope for them to come up with something I can use. I'm aware it's not gonna be cheap, but since this will be the long-term solution I don't mind spending on reliability.

Inj the near future I might just change the wheel studs for longer ones and run a huge spacer. Maybe rolling the fenders a bit too if it still rubs. This is all I can afford right now so it's gonna have to do for now
I gotta admit I didn't think this fitment was gonna be so complex but I'm actually enjoying the solving proccess.

Thanks again for adding to the post!
