Cant get to my back plugs

I am unable to gain access to the back three plugs on my engine. This year of vehicle made things very difficult and they didnt fix this problem until 2 years later when they brought the engine further out away from the firewall. I have tried everything to gain access to the back three plugs. Is there a way for me to get back there to change the plugs? Please be as detailed as possible as I am not a mechanic and cannot afford to hire one
