It was a grommet... now it's a torn grommet. I have a good amount of orings. Tore the thicker one as well trying to get it in. Ended up using a thinner oring that I could double up. The rod is all secured in the MC now.
Yes its the adapter with grommet from DrDiff... the MC is not from DrDiff... its actually a 7/8 bore MC from a 90s dodge, have seen some guys on FABO run the 7/8 bore MC. I couldn't bring myself to pay 100 bucks for an MC from DrDiff...
I'll bench bleed the MC tomorrow. Was hoping to have it done today so I could drive the car to school tomorrow but life got in the way lol.
Edit- this is the MC I got Dorman M39736
15 bucks shipped to me off Amazon... it was an open box, gosh I love open box item prices on Amazon with free shipping.
