Brent, the deck is indeed spot welded in place. The biggest challenge is the support under the deck at the front and the rear, as well as the tab connecting to the two forward deck pieces just behind the doors. It is also welded to the inner rear fender. As previously mentioned, take measurements, and if I may suggest, use your fenders and trunk lid as a guide when you fit and tack the deck in place. You may also want to consider getting the ~$400 spot welder. While it will not reach all the weld points, it will help at the front and back will and eliminate the need to grind the plug welds.
