I had a skunk 2 shifter on my ek4 sir and that was the same, to narrow for the non type R linkage.I had bought a buddy club dual bend for my ek9 but it was too narrow at the bottom bearing end for the fork in the linkage even with the spacers.
Think so mate but my Ali express k tuned shifter fits. You could probably make up spacers to make anything work tho.
