T-40 'guards aren't hard to come by. Someone on eBay is always selling them made out of all kinds of materials.
Those pickup surrounds though, think twice about throwing them out. In fact, don't lose one single piece of that bass. I once lost a saddle for a T-20 and those just don't exist. I eventually tracked down Chip Todd himself (who designed the T series with Hartley Peavey) and even he didn't know where to find one.
So...be careful! At least the T-40 is a bit more common, but if you need to replace some part of it you typically have to find someone who has one parted out...and those people are hard to find as well. Everybody it seems has a T-guitar they're trying to fix up.
