Bergman Auto Craft Delrin Bushings and Pivot Pin Pkg Special use code BAC10

@BergmanAutoCraft I’m interested in the pivot shaft-Delrin bushing kit P/N 7-1008. The picture shows the pivot shafts without the notches/grooves but you also offer just the pivot shafts (P/N 5-0063) specifically to use in combination with the Delrin bushings . Is that just a photo that hasn’t been updated or what exactly would I receive if I order 7-1008?

I’m assuming those notches on the pivot shafts shown for 5-0063 is for the grease to live in so you don’t have to regrease?
Is there any assembly procedures or adjustment needed as the stock LCA bushings sit flush and the delrin sticks out ? Do you just tighten the **** out of it and it compresses? Maybe it doesn’t matter? As I haven’t seen anyone mention anything regarding that, just going by some observations from pictures seen on the site .
