It's been a while now, but I've done a billion mustang clutch jobs. I seem to remember it taking a sat.
however, approach this in two stages.
the first weekend install the clutch pedals. It won't take the entire weekend, but it'll take long enough to completely throw off your sched on the rest of the stuff enough to make a sun deadline difficult.
the next weekend, lose the aod, pull the center console, lose the shifter assembly...fyi I cut it up/bent it, mutuatled it to pull it out. don't waste your time trying to pull it out as a complete assmbly, that'll take too much time.
if you have all your stuff lined up, it'll take maybe a couple more hours than a normal clutch job would, and that's just because you've got to remove the aod lines and shifter.
it's absolutely necessary to have EVERYTHING lined up and ready, or you're gonna blow your deadline.
some specifics to keep in mind that will completely mess you up if you're not prepared.
1. metric pressure plate bolts. frpp sells a cheap kit, less than $10, pick them up from summit
2. get NEW flywheel bolts. at 85 pounds of torque, it's cheap insurance. FYI, the automatic flywheel bolts are shorter, so be sure to run the manual ones, or the arp ones. arp ones less than $10 at summit
3. the top two bell housing bolts on your aod are too long. have a stack of washers ready to take up the slack, or a cutoff wheel to shorten the bolt.
4. get all the tiny stuff such as the clutch cable clip, the clutch cable, and even stupid stuff you may overlook like the shifter to trans bolts
5. if you want to be extra prepared, buyfordracing.com has a NEW HD clutch fork and oem clutch cable for under $50 to your door.
6. if you haven't had too many manuals b4, break in your clutch for 500 miles, which means NO full throttle from a stop or even while in motion, this is VERY important unless you enjoy clutch jobs.
