did install Sat morning and pulled the old one out Fri night... woof.
items needed:
10mm wrench for hard lines
12mm wrench for cmc rod adjustment
12mm socket for cmc bolts and booster bolts
10mm socket for cmc reservoir bracket
8mm short wrench for slave cylinder bleeder
swivel for left cmc bolt
needle nose for cmc pin and hard line clasps
unbolt cmc and disconnect pedal. loosen booster bolts as much as possible
unbolt cmc reservoir
disconnect hardline along frame rail
wiggle booster while pulling out hardline
wiggle out cmc and hard line all in one including reservoir... under brake reservoir
swap over needed parts from old cmc to new
reinstall
bleed via slave cylinder

Per ACT, they have come to the conclusion the feedback plate (triangular object at end of CMC) is to blame for failure

Hmm... I wonder if our XLR8 CMC upgrade would work then.

Yea... it would work. However, the EM2 that I used is a direct replacement and needs no other supporting compenents like the EM1 needs(the ss-line and fittings).

So... ~$25 for EM2 or $150+ for EM1.... no difference in performance or function between the two... EM2 is where it's at for the money.

have been hearing creaking noises from the clutch pedal, just installed a new cmc a few weeks ago so I knew it had to be the bracket
my buddy welded the seams. fixed it. a lot more sturdy with less deflection. the entire pedal throw is more smooth
