Center drag link, are they really $600? 1964 dart

Looks like I'm not willing to pay what they're worth to be honest. Rather go the not bill my hours and pretend I'm saving money wasting time making something myself. But if folks are saying it's super close to working I'm gonna give it a try with the slant 6 link.
Put up a WANTED add here , someone may have one at a better price than $600
