I have mine apart just now for an upgrade of the axle cage on the trans end. CRW supplies kits for this and you should consider if you have disassembeled.
The bolts holding the carrier bearing are the same for all turbo's. Not sure what the size is but something like 14mm head and is high tensile strength. Either contact Josh at CRW (aks mister3) or your local Toyota dealership for replacement.
