K10 Cab Mounts...need second opinion

[sdailey]

I bought a complete cab mount kit (Counterpart #67-5001) a while back and I need a second opinion on where they mount. The kit didn't come with any instructions so instead of totally guessing at this I hope someone can confirm what I'm already thinking.

Looking at the attached picture, the mounts circled in red are for the rear of the cab and the blue circled mounts are for the front cab mounts?

If this is correct what are the other mounts (4) for? Core support maybe?

Also, do I use the metal sleeves in the front bushings?

Thanks for any help.
