I know this has been discussed before. I did the search but couldn't find answer to my question...which is this:

From reading the forum, I understand that a hole must be drilled into the Rotex Gold pad for the sensor to fit through. Where is the best place to get these pads...and...it there a brand Rotex Gold pad that you don't have to drill?

Thanks!

P.S. Andrew, I found through the search, your detailed instructions on installation. Great
