I'm taking ownership of a cb70 but have no idea on where to find parts

I'm planning on a full rebuild and want to give it a full balance and tickle to get it embarrasing commodores wrx skylines ect as I will be fitting it to a 2 door g11

I used to have a g11r running 21pound boost in a cb60 and it was great looking at peoples faces at the lights.

Now 13 years on and I'm feeling a little nostalgic and since my budget is bigger than when I was 17 I wnat to build a ball tearer of a mini sleeper.

Any help will be welcomed guys
