Which throttle cable for a '75 UK RD350

[cbm]

I posted the question for my computer illiterate mate over on the A/c site without much luck so appreciate any info, maybe Norbo can advise. 
The bike's '75 UK RD350 the chassis number starts 521 and it has the high top carbs. I've already been told the OEM ones aren't available if so any recommendations re the pattern options available will be much appreciated. 

Cheers

Yamaha in their infinite wisdom list the throttle cable in 5 separate parts so you cant buy a genuine item as a single unit. I had a similar problem finding a correct length cable for my UK 350A but managed to coble together a complete cable using several different ones that I'd bought over the years. I had at least half a dozen cables both OEM and pattern and no two were the same length !



I know Yambits sell a cable for the 350 high tops but have no idea of its quality or whether it fits.  Have a look at the link below.
