Flat rate repair will repair everything or replace the entire tool. Bodies generally only get replaced if they're cracked or if something like the rubber over molding has come off. If it just cosmetically looks like trash you may get it back as the 725 was replaced by the 714 a while ago although if memory serves the 725 and 761 (3/8) shared the same bodies so it should be entirely repairable. It would probably run you about 100CAD if I had to guess but also covers shipping both ways, at least in the States. Worth it if you're going to spend anything close to that just on parts.

It may also interest you that they sell replacement housings for the 14.4 batteries if those are chewed up. That's part number CTB8172-1, includes both halves and screws, and cost about $10
