OK, this is very had to explain, very techy!!!!

     Where can  I find a (RED) Distributor cap for my Y-Blok
I know this has to make some of you laugh, and I have searched the net and can't seem to find one for sale
yet I see them on  in photo's of Y-Blocks all the time...
A web site or part No. would be nice
   I bought a cap at NAPA,  (made in china)  he got the cap back...I'd use the old one first..
Best
