Update:
Alright folks she's installed!
Took me a little over 2 hrs to R&R it all. Yep, pulling the pedals is THE way to go about this & using a vacuum pump w\ bleedout container made short work on bleeding the new FoMoCo 13-14 GT500 MC....got a good firm pedal in 3 pump cycles & a full feed line w\ no bubbles.
Plugged the nipple on the brake reservoir to stop it from leaking while doing the R&R then pulled the plug & installed the bled out MC feed line to the reservoir so didn't need to get a stopper then pulled the top off the reservoir to allow what little bit of air that got trapped at the reservoir nipple to bleed out....done.
I found that I had a pair of long handled 45* angled needle nose pliers that allowed me to reach the clutch line pin in MC & pull it w\o having to move the AC drier then use a long flat blade screwdriver to separate the clutch line (Ford Performance SS Solid Clutch Line) then since my clutch line was a solid SS piece this made it easier to put it back in as it is formed to the right angle & position so I just used my long handled NN pliers to grab it & snap it back in the MC once I got the pedal assembly reinstalled.
Entire job was very straightforward actually...…………...but I'm feeling it in my shoulders, back & neck muscles......
This Ford 13-14 GT500 MC did indeed gain me more usable stroke vs my PowerTorque HP Clutch MC (all metal construction but designed to the Ford OEM plastic MC specs) so instead of the clutch starting to grab w\ the pedal at 2" off the floor w\ the PT MC, it now starts to grab w\ the pedal at 3" off the floor w\ the 13-14 GT500 MC & instead of the 3\16" of slack I had at the top from the bump stop I now have about 1\8" of slack. Pedal feel\feedback is much more firm\solid now than it was w\ the PT MC & she slides in\out of gear much better (especially when downshifting) so this FoMoCo part# DR3Z-7A543-A 13-14 GT500 Clutch MC is a winner indeed.
Can't go wrong w\ this part. Only thing I regret is not knowing of\acquiring it sooner...…..
