GLC63 AMG rear diffuser on GLC43
My GLC43 bumper trim was recently damaged and I need to replace it. I like the 63 version much better, but I am not sure if it will work on the 43. Can anyone comment on this?

I don't believe the exhaust cut outs are the same shape and size.

That is correct the exhaust tips would have to be switched, but thats no problem. I just dont know if the diffuser as a whole is a direct swap or not.

If you're talking about the entire rear bumper and diffuser I would assume it is. All of the surrounding metal etc. are shared parts between models so I would think it would work.
If you can go to a dealer and park next to one.

Did you ever figure this out? I'm looking into swapping to the 63 coupe diffuser and trying to see what parts are needed?

I swapped the whole rear diffuser on my 43 to the 63, you just need to get all the parts but it fits.

Thanks. Do you know what the parts are? So far I have written down the following but not sure if all is needed or if I’m missing some.

- Lower Trim Panel
- Tailpipe Extensions aka Exhaust Tips (Right and Left)
- Tailpipe Extension Brackets (Right and Left)
- Diffuser
- Deflector Shield
- Deflector Panel

Do I need the Tow Bracket Cover and Side Retainers (Left and Right)?

So far parts are right around $1400 shipped. When they finally arrive I'll see if I'm missing anything.
