Another AlterK question (engine mounts)

Ok, lately I'm feeling like a 12 yo newb at this. Just tired. Trying to get this done before fall. I want to install the engine mounts, that came with the AlterK kit. Well, they are not marked pass or drivers side. Also, It mentions, in the instructions, that I might have to grind the boss on the drivers side, so the mount fits.
Would love some pix of the mounts installed on the block. And, has anyone needed to grind the boss. How much and where?
Thanks
