Throttle bodies.. Are they all the same?

Done a quick search but can't find a answer..

Are all or at least most throttle bodies the same on mk3 clios?

I.e, 1.4/1.6/2.0


I'm a machinist so I'm going to bore one out myself at some point and I've found one that looks the same but says 1.4 1.6.
i gather 172's, 182's, 197's and 200's use the same throttle body just not sure about the smaller engines.

Thanks in advance.
 
I think the size is slightly different but if your interested i have a standard one from my 200 for sale
