I have tried the mounts with an EK subframe and an EG/DC subframe and the mounts don't line up. I bought the mounts used from someone that told me they were for an ek. I've done some searching and found this link, comparing the pictures of the ek mounts andthe eg/dc mounts I am convinced that they are for an eg/dc.
