After checking the differences between the old brake booster and the new one, I noticed the rod on the master cylinder side had a different length. The old booster had some sort of stick on the end of the rod. After a wile I found out it could come off with pliers.
Time to fit the booster!
BTW, the clip that attaches the fork to the pedal was a bitch to disconnect but once you understand the way it works it’s easy 🙂
Then I mounted the intake manifold to find out the clearance with the brake booster.
