my question is, the US EF civic cx has the seat belt on the door and I wanna change the door to the Canadian EF door, is it possible? Also does the US civic body have all the holes to put the beat belts in it?

 

It has the top holes but doesn't have the nuts on both sides. On the passenger side it has the bottom nut and it has nothing on the driver side.

 

but can I swap the doors or not?

 

Yes

 

search around, there's a thread in the archives i believe that shows that the frame is actualy curved different, and while the non seat belt doors do fit on the cars with the door mounted belts it chews up the door seal badly. there is also a wright up around here about how to install weld nuts in places that need them.

 

I saw all that but they were for CRX's not for EF hatch.
