I recently bought a used SS GGTS and new stealth cap from COV. Shouldn't all threads be compatible? My SS top tube will not screw into my main bottom tube nor my new stealth cap. And one end of my telescope tube will not screw into my main bottom tube nor my stealth cap. Both ends of my rethreader ring that came with the stealth cap threads on everything including the collector tank. I have seen pictures of the TS in every conceivable configuration which leads me to conclude that the male threads on one end of my telescope tube and the male threads on my top tube are defective. Can someone confirm this?
