You don't say whether you already have a title or not. If you don't have a title now, they will use your vehicle serial number from the left doorpost, not the engine number.
If you don't have a title it will have to be inspected by the highway patrol since it is not a pre-1950 vehicle.
Make sure you call the highway patrol inspection station before you go to make sure of the hours and whether or not this is a special inspection requiring you to go only during certain hours.
Then I believe, you can take that inspection document, your bill of sale, proof of insurance and your checkbook to a county DMV.
Spend some time on the KS DMV website or call your county DMV office. Their answers to your questions are the only ones that matter.
