1) This is actually a N/A lower diagram but the TC manny is pretty much the same, except a nipple goes where the fan switch is, to route the small coolant hose from the lines that go into the oil cooler and there are 2 holes on the side of the TC manny. The lower one is for the ACT sensor and the upper one is for the knock sensor.

2) Rubber hoses on the ends of coolant tubes. I had several preformed heater hoses laying around so I cut the 90*'s off and adapted them. You can still get the correct hoses from NAPA but they're pricey. Here's a diagram and pics of mine.

3) On TC's the oil feed goes into the distribution block. I'm running an aftermarket mechanical O/P gauge and Stinger oil feed line. I picked up this adapter and a couple of brass fittings at NAPA. The oil feed screws into the top and the copper line for the gauge screws into the end. Disregard all the writing. It was for another post.

4) Oil drain fitting screws into the block, passenger side, down low. You can't miss it!

Stinger sells oil drain flanges and hoses.

5) On the cartridge between the compressor and turbine housing, below the oil feed fitting on each side are threaded holes. If you don't have the factory fittings, go buy some at NAPA. The feed line is the hole closest to the block and the drain is on the other side.
It's best to go with metal lines that close to the turbo, however, I use high-temp (silicone, I think - black on the outside and green on the inside) heater hose, again purchased from NAPA, on my daily driven '86 TC. Been running it for almost 3 years with no issues.
6) Your buddy is right. It's not on the T/B, it's on the upper intake. Cut the 90* off so it doesn't hit the V/C and run a hose off the straight part. It's simply a vac port into the upper intake.
7) You might have to fab some new mounts, but you can simply slide your radiator over a tad so the I/C pipes will clear.
8) Are you talking about the high-temp heater hoses for the coolant lines? If so, see #5.
Other things to do:
a) Fox bodies have inherent ground problems. Cut off the heads and weld some bolts to a small plate then weld the plate to the frame. One on each side. Here you can attach your NEG batt cable and a couple of ground straps.

b) Relocate your TFI. The below writeup is on my '86 TC. I did the same procedure on Thunderstang, minus the SS heat sheild.

c) Rebuild your distributor and install a new PIP.

d) If you're feeling creative, build a turbo heat shield. It really helps keep down underhood temps.

e) When the time comes, this vac diagram will probably come in handy.

That's it for now. I hope this all helps.
