Pricing for the 24x rings and related pieces is now available at http://www.eficonnection.com/eficonn..._cylinder.aspx
We have a very small quantity of the GM distributor caps. They will only be sold to those who are purchasing a 24x ring, 24x sensor, and are currently ready to do this conversion. If you are not ready to do this conversion, I'm going to ask that you wait for us to make new (non-GM) caps. We are currently working on this.
