They're not going to fit through the fork without a bit of work to narrow them where they pass through. I have the VO 63mm fenders on my Appaloosa (they actually measure 63.5mm), and there's only a fraction of a millimetre clearance each side where they pass between the fork blades - I fitted plastic frame protector dots on the inside of the fork blades each side to prevent the paint being worn off by the fender.
The rear should fit OK, but it will probably need an indentation on the drive side just above the chainstay to clear the chain when in your lowest gear. The VO 63mm fenders come with this indentation already done, but looking at the Tanaka fenders on the Soma website, I couldn't see that they are similarly treated.
