I managed to fit V brakes to mine by moving the noodle that is attached to the frame.
You need to get something like a ratchet bit holding screw driver without the bit in it to fit over the end of the noodle. Carefully bend the noodle so that it curls around the seat tube. This lines the noodle up with the position of the cable outer that goes to the noodle on the V brake. See picture. I'll take a close-up pic tonight
It works ok
Hope this helps
