I have decide i will completely replace the ignition i have. it has failed. The new FAST xr 700 is what i want for my 68 sprite. But im not sure on which one to get theres several. Called moss motors and the young boy said they all work. When i started asking questions he went blank. Put me on hold then i was cut off. Anyone know if the XR700-2301 would be correct? Im gonna replace coil, and the complete system. Thanks for any advice.
