Looks like the info you already got was correct. Here's how you find out the year. On the back of the block where the bellhousing flange is, up from where the casting numbers are the date code is cast into the block. It will look like this example:
D 6 9
D is the month. D is the 4th letter so the 4th month: April.
6 is the date of the month: 6th Of April
9 is the year. Depending on what years the casting numbers was used will dictate if it was cast in 1969, 1979, 1989 Etc.
The date code can also look like this example:
D 6 79 Which works out the same as above only it's giving you the actual year. I don't know what you mean by sensors. The old school cars before the computer days didn't have sensors. They have Temp gauge sending unit, oil pressure sending unit and not a whole lot more so you'll have to get more specific on what you mean by sensors.
