Can I ask why you wouldn't just buy new ones?
Yep reasonable question! The repo products like DC are good, but their not perfect. If your wanting to get the whole colour scheme back to original, the only way to get 100% is to use NOS or restored plastics.
For a full nut and bolt resto, restore the plastics. for racing the DC stuff is fine.
If i had some prepared stuff here in Oz, i would bring it up to Bulahdelah for you look at, but i'm still waiting for it to get back from the US and i have not finished my restored plastics yet! But, when i do, you can see and feel the difference:)
