I have an a180 without the amg line (i have made all the amg line exterior changes) and i would like to change the steering wheel with the amg line one (code 772). It is a manual transmission with no distronic and i have found the steering wheel that matches with the airbag inside and ready to be fit. Is the change possible (like plug and play) or do you need to mod anything? In the pictures you can see the two different steering wheels. I have checked a lot of them and i noticed that the back was different in some of them (it was the minority).
