Garth,
I will be needing new rubber strips also. I saw these on the Graham Pantera website a while back. I never got around to ordering them and now, I cannot access their website.
Now I see these listed on Wilkinson's website. They have the strip for the tank strap and show the 'thin style' strips for the tank. I'm not sure if there is supposed to be a rubber pad under the tank. My car did not have a pad under the tank, it seems that the tank would sit too high with one. Let me know what you come up with.
