W123 230CE Front Wing Replacement

[gizzardio]

Hi All

I just picked up a 230CE W123 and after a few months previous filler repair on the front wings is showing through in places. So i want to just swap out the wings and re-spray.

Is there any advice on pattern parts that anyone can offer? I've seen loads on the internet but you never know how the shut lines and tolerances will be until you fit it.

Any advice appreciated.

Thanks

Rob
