Removing the seals: Not too bad, actually. I followed part of the factory advice and used a flat screwdriver with an old heavy fabric napkin over the tip and stuck it in next to both the crank and the cam to open up some access (this keeps you from scratching the cam/crank). Then I employed another nearly-forgotten thing from my old friends at Harbor Freight, a set of little picks with curved ends. I just snaked them in carefully, avoiding the inner surfaces, and pulled the seals out. Went to Walgreens and got some Q-Tips, then cleaned up the areas where the new seals will go in with the tips coated with a spritz of brake cleaner (lots of 'tips), then used dry ones to do a final clean and check for scratches (none; no shredding of tips).
After a fruitless session of trying to use various sockets and household implements to drive in the new seals, I used my fancy caliper to determine that a 1-1/2" and a 2" section of schedule 40 PVC fit the seals just right, so I went to Home (away from home) Depot and bought a short section of each, plus end caps to use as hammer points. I'll shorten those down in the morning, smooth out the business ends and should make short work of seating them.
I also picked up a section of perforated flat steel stock to fasten to the bellcrank so I can attach the transmission kick-down cable. Of course in the process of removing the throttle body, I saw the need to replace the cooling lines that run to/from that piece as well.
Reassembly will commence tomorrow. It better, anyway.
