Fabricating the riser block is the hard part. Riser needs to be steel/cast iron due to the load once you put tension on the blade. The kit consists of the riser block, a guard (rear), a new guide post, (mine has a 15/16" but some have a 7/8"), an extended blade guard (front), and a new 105" blade. Heard some folks are using a Grizzly riser with their Deltas'. Kit is similar other than the alignment pins don't match. Some woodworkers just remove them and alignment the unit themselves. You could also just reposition the pins. If I was to do it over, I would go the Grizzly route. A company down in Florida is very helpful if you need info, call them at 904-642-2802.
