Don't tell me ask sunray, I did and they are of no help. Some of the Treasure Coast guys are having their cz-20 machines hardwired with the Sunray fz-20 coil and tuned by a local tech down there. Can anybody put me in contact with this person or provide any info? I am headed down there in late winter to Vero and vicinity and would like to ship my cz-20 out to have this done so it is ready for the trip. My Excaliber is going in for warrenty work this week so that should be ready, but I would like to have the mod done on the cz-20 in time. HELP! Someone has to know the contact info for the tech doing this.
