Throttle Cable

I think I may need a new throttle cable soon. Last event I did they paid a little too much attention at my slightly frayed cable during scuitineering.

I checked out your site and the cables are exchange right?

How does the exchange system work do I send my old cable then get a new 1 or do you send me a new 1 then I send you my old 1.
The reason I ask is that I don't want to miss an event in our local series because I am waiting on a cable (can't afford to miss out on the points).

some cables are repaired and avail on exchange and others I need to do yours. some need to be new as they are not worth repairing. let me know EXACTLY what car you have. send me frame and model details off the Toyota ID plate
