I was thinking of purchasing the cap, rotor, and gasket and was wondering if anyone has purchased them from here and what their experience was like? Thanks

 

I believe there is a cap made in China, yes, I know, that actually uses brass terminals like the original. Not sure if they are any better than the ones made with aluminum but can't be worse.
