Where to get linkages
 

I am looking for a replacement female-threaded 1/4"socket ball diameter quick disconnect for a throttle linkage. Similar to the ball-and-sockets used in the throttle linkages in our 911's but this one is for a BBK 80mm throttle body (for the supercharged car.) Same female threading (0.8mm or 28-) but with a slightly smaller socket to fit a slightly smaller ball. No luck at Grainger, Mcmaster carr, etc

Ford dealers only carry the whole cable and they say in any case the socket is swaged to the cable.

I lost the original and I dont know who made the cable/linkage in the first place...that guy was in Australia and it was done at the shop while I was away.

Mcmaster carr doesnt have the right size...wurth doesnt have any...any suggestions for mail-order linkages?

Thanks
