It is a simple change, all you need is something to hold it (soft jaw vise) and a torque wrench with long-ish Allen key heads. The nut on the yoke is going to need a custom socket (thin walled) to remove it. Depending on condition, you may need to replace the o-ring (not included with the conversion) that goes on the retainer.
As to warranty, who knows what shenanigans may come out of that. Somehow I think SP is trying to find anything to kick folks out of FPFL (lets not go there in this thread).....
If you are due for service, and don't have the tools, maybe your tech will swap it out then (see if they will beat/match the price you can get it on-line).
