Turbo and non-turbo throttle bodies?

Sounds like a dumb question, but I couldn't find any info on this subject.

Can TII and N/A throttle bodies be interchanged. I know S4 and S5 are different.

teh tps's are the same for S4 and S4 TII.
Now,I looked at an N/a and a TII TB and noticed there are some differences,BUT if you have a Bad TB and can swap some **** out,I THINK you can make the N/A into a GOOD TII tb,
It has to do with linkage locations,and pieces in that area.The Air intake Holes look to be the same size,..I didn't notice the bolt pattern for the nose piece though(intake pice to attach to the Front of the TB,
UNLESS by mistake I sold a Throttlebody to someone that was supposed to be the oppsoite of that they ordered,.,MY BOx now contains TWO different TB's and they are supposed to be N/A and TII respectively./

N/A's and Turbos have throttle cable linkages in opposite directions. This can be overcome though.
