MAE CROWN WHITE JEWEL

Hello dear community ) Have a problem again and turn to you again here has always helped me THANK ALso, I have a set of MAE Crown JEwel rims in 20 inches, have let them now completely high gloss polish and the dinger look out…wow…hammer…unbelievably beautiful has always been MAE fan (cheap thing)!! So now the problem, the previous owner has no data or papers at all for these rims and now I stand there. I want to mount these on my CL420 W140 But I had to say to myself from the tyre depot in Steinfurt that it is not possible in this combo or that these rims in these dimensions ( front 9j x 20 rear 11 J x 20) were actually intended for the SL. I can and will not sell the rims and want to mount them on them. Who of you can help me B I T T E!!!!! or give me a tip where I can download such a report ( ABE ) for the parts? That must be there somewhere. I already have so much money for the polishing and the new tires I really don’t want to cut out a lot of ash for these reports and the subsequent registrations, because they are not even registered… unfortunately ( Please help me a little, who knows themselves??? Thank you very much already in advance… TONI
