4b11 block differences at the crank?

Has anyone put on an aluminum pulley on a 2013 Lancer with a 4b11 motor?
I've ran into an issue with the 2013 Outlander Sport's 4b11 crank area. there are some ridges at the crank area that won't allow the OBX pulley (or the RRM for that matter) to sit snug to the crank. I think the new 2013 motors have this addition to the casting on the block, can anyone confirm this on their new Lancer?

looks like you need to grind a little off of that protruding part in order to make it fit

I ended up doing that sometime ago.
I gave some of the measurement info to another company so that they could work on providing a pulley that would clear the ridges in the new blocks.
Ended up trading the 2013 Outlander Sport for a 2014 Outlander. Now I'll have to see what difference those Blocks are compared to earlier 2.4s.
This will get a pulley also. The throttle response on the OS was MUCH nicer.
