Center to center motor mount measurement?

Like a dumbass, I didn't measure between motor mounts when I replaced the imploded stock mounts with new Brown Dog mounts. I'm going to drop the new engine in today and don't want to mess with tightening the mounts AFTER the engine is taking up the space to do so.

I've searched everywhere and cannot find the numbers that I'm looking for.

Does anyone have the numbers, or should I just suck it up and do the tightening after I've connected the engine to the mounts?

Any input is appreciated.
