Got everything I need except for the LS-30's. Not really wanting to take these all apart to make a template if one already exists.
Thanks again.

Are you bottom or top mounting? Either way, getting it exact should not really be a big deal. A recess with even a full 1/4" extra space all around doesn't look any worse than a exact tight recess, and will still be structurally sound. With just hand measuring you should be able to get it within 1/8" easy.
And if its a top mount, just fill it in with wood putty once mounted, its going to be covered anyway (I assume). Measure the mounting plate, and sketch it out as necessary.
