Help needed with Hargett shifter

[jakz]

I just bought a used hargett shifter and its missing some parts, I've been able to find pictures on most of them to fabricate them and make it complete but I'm missing a detail on how the centering spring works. If someone has one that could take a picture for me that would be greatly appreciated I was able to find this pic but it doesn't show how the springs get attached to the "pipe" maybe I'm overthinkig it and its just another pin but would like a confirmation if possible.

Thanks in advance

Ps. If someone has some spare parts for a hargett I'm interested too
