You asked: "so the throw out bearing conversion piece fits into the end of the actuator arm where the carbon disc is?"
Yes. Instructions come with the new throw out bearing assembly.
Regarding the photos:
1. Dunno. Maybe a gas tank strap from a car, not a truck. The gas tank goes under the seat in the cab. The correct straps have a 5/16" T bolt riveted at both ends of each strap. There should be tank cross members on the chassis to support the gas tank.
2. Possibly cab parts. Not sure.
3. The rail on the far left is for a floor board support for the slanted boards that go from the firewall to the cab floor. The top board will have a hole for the pedals. I have no idea about the other parts.
4. The other support for the slanted floor boards.
5. The push rod covers are for 1928 only. You'll see that your head has side lips that would contact the side of these covers, but the block does not. Those side lips on the head continue down to the block on a '28 block and the '28 block has the bolt holes for those covers.
6. Two things to note about this side view of the engine.
A - The hole in the flyhweel cover is where you should see a U|C when the first cylinder is at TDC on the compression stroke. There is another mark on the flywheel for 25 degrees before TDC. You'll use these marks to statically time the distributor.
B - The top radiator connection is from the '27 engine. If you want a thermostat, get a '28 radiator connector, which can house it.
