Addressing the transmission and failed starter motor. Replaced starter which broke at the starter gear housing, and while the ZF-5 transmission and drivelines were removed from the truck, went ahead and had the following parts replaced for $1000 in labor: flywheel, engine rear main seal (Ford p/n F4TZ-6701-A) pressure plate, clutch, shift fork (Ford p/n E7TZ-7515-A), clutch fork pivot bolt (Ford p/n E7TZ-7B602-A which is no longer manufactured for the discontinued ZF-5 transmission), and throw-out bearing.
In retrospect, would have been a convenient time to replace turbo up-pipes, and address any exhaust manifold repairs such as broken studs. The 3″ Diamond Eye down-pipe from the turbo-back kit is holding up great.
Solid model file for shift fork ball pivot (discontinued ZF part). LINK
