Hector,
It’s been several years since I bought the, for want of a better word, Pink Block Connectors that CC used in the past. At that time I did some research and found that the vendor was in Seattle but as I recall they had ceased operations. I am sure you have tried CC Parts however you may want to check with CC Service as an alternative. Those electrical connectors were widely used on every model of CC; that said they surely would have a line acceptable substitute. Also I might check with Miles C. who purchased many of the spares from CC, he may well have additional information.
