Exactly what size drum brakes does my car have?

I'm ordering some new brake parts and I need to know exactly what size drums my car has (without pulling wheels and measuring). It's a '69 Valiant Signet, 4-door, 225 slant with a 3 speed auto, no A/C, power steering, manual drum brakes all around with the VIN: VH4IB9B350855

I should have 'er rolling again within a day or two and I'd like to get all of the brake components ordered now so I can install them next week sometime. Thanks for any replies. Many of you have been a big help in the past.
