I figured this out I believe...The Pins that I received from Perseas are longer pins for the PAPS X. There was a group buy on another forum and there are some that did not get the long pin due to early release of the PAPS for them as I have mailed a couple in the past.
Here is a picture of the pins. The pin in the middle and the pin on the right should of been in your PAPS V3 delivery. The shorter of the two was most likely installed upon arrival.
The longest pin on the left is the longer pin for the PAPS X.
Please note, the length difference between the middle pin and the pin on the left is slight, maybe .5-1mm. Perseas will have to correct me if I am mistaken.
