Yes ru 11 was the original resistor in the FBO kit.

You can buy them anywhere, and keep using them if you don't mind changing them once and a while.

Then they went to the .8 msd.
I sold lots of those when I was an FBO dealer, and use them in my own stuff. Never had one go bad, but who knows where msd makes them now.

For what one cost's I wouldn't be afraid to try one
