Michel, the measurementsjust don't add up - the lengths and shapes are different - plus a host of many other items.To give you an idea - some years ago, in fact many, I bought a 280S/SE front inner guard to fit to a chassis 109 6.3. The detail differences were mind boggling and took ages to fit and fix.
I tend to think that Helmet is pretty well spot on - also, don't forget that he does own a 220SE Coupe and I daresay that he'd be pretty familiar with some of the issues involved. Regards Styria
N.B. Michel, I am even confident in stating that 220SE and say, 280SE 3.5 Coupe bonnets and front guards would not be interchangeable. How say you, Helmet ? Agree ?
