Help with identifying various holes on '71 340

Pic 1 top left is coil mount hole, second hole has bolt in it already.
Pic 2 Could be ballast if its an older car with single ballast.
Pic 3 Possibly NSS wire if its an early car. Im not exactly sure what year they switched to the three prong switch, probably around 69?
Pic 4 Yes, correct sender for light. Gauge sender is much bigger metal can.
Yes, coil wires. Should have D shaped hole in the terminals.
The choke well is factory piece, not a block off. However, your missing the top part of it. Perfectly fine as is if your going electric.
Pic 5 Big holes are locating holes for alignment when block was machined. They serve no purpose after the fact.
? hole may be block drain(antifreeze) and would have a 1/4" NPT plug in it.
Other hole is for the support bracket that goes to trans. However, they sometimes wont fit with headers.
Those links look like the correct parts but you can get them much cheaper. Check at rockauto.com .....not sure if they ship to Sweden.
