Sorry mate I believe he sold all the old stock off that he had left, the only ones he had when I last saw were S2K ones, Will at TGM Sport in Fleet did mine for me in Spoon Yellow, they were really good and the finish spot on. Lasted fine the whole time I had the car and mine was only ever used on track pretty much so was always getting very vey hot and being pushed hard@carl - are you able to find out if he has any DC5 rocker covers available still? I doubt it but if you don’t ask..
It's not the hardest job in the word but also not as easy as you'd think. As I have said to Paul, I would recommend Will at TGM sport for the job, my build thread shows how mine was and it lasted no issues until I sold the car with extreme heat cycles constantly on and off track for yearsHi.
I think we're out of luck. I might have a go at doing my own. There's plenty of info how on Youtube.
