Which Rear type u brake for this dyno 98?

[Benharcombe]

Just bought this to use for the shop runs and chasing the nippers. My issue is I'm stuck as to what rear brake I can use I've tried a rear tektro off our lads 2010 gt bump but the arms seem to short to reach 



This is the bike after me fitting seat & rear wheel ,if anyone knows it stickers say CT instead of GT after asking previous owner it's some bike shops old gangs bikes if anyone knows anything CT cycles

My 2002 Gt Zone came with generic Tektro U brakes. Its had a Ombre on the back and now resides a Oddy Evo2.
