Okay, that photo is a lot more clear as the other photos we a bit fuzzy in that area.. What I was seeing was the brass T.
Now it would have to be trimmed to fit.....in CT termsSweet Jesus if you didn’t already have a great CT…
“Forget how much I cut off but definitely made it easier to slip it in.”


Way back when I did mine, there was a weird bump in the tower about the size of a nickel that l had to hit a few times in order to get the booster past.Sand-filled mallet on the booster to tap it in maybe? I didn't touch my tower at all when I installed it into my '88. 1990+ are the easiest install, but pre-90 is still doable without resorting to drastic measures.
One interesting thing I experienced though is that the brakes have less initial bite to them. Very light braking requires more effort than before but heavy braking requires significantly less effort. Anyone else notice this? I expected the pedal to be more sensitive across the board but it's not like that at all.
There's dirt cheap tool to set up the booster rods now.. Snagged a few off temu for less than $5This makes me wonder if the initial brake adjustment and break-in are completed.
That feeling might be coming from having to take up that initial play between the pad and rotor surface.
The other thing that comes to mind is the adjustment of the MC rod into the booster.
That's all I got.
