You should probably start a new thread for new questions/problems.

Looks to me like both the lock and the switch from 1987 will fit your '73 with no problem.
Both 911-613-904-00 and 911-613-902 parts numbers are given in PET for the lock from 71/72 up; PET gives 904 as "state lock number" and "902" as "without stipulated lock-no". 911-613-902-00 is used up until 1989.
The ignition switch (the electrical portion) had the same part # 911-613-017-00 from 72 up through 84, according to my PET. From 1985 onwards, the part # is 964-613-012-00.
The original 911-613-017-00 switch has been NLA for some considerable time; the replacement is the 964 part, although they're not quite the same...
My '77 original ignition switch had no lockout in the electrical portion; once that is removed, the key turns freely anywhere you want in the lock. And using a screwdriver in the electrical portion, take it all the way from Off/Acc/Run/Start, let it go back to Run and hit Start again as many times as you like, no problem.
The 964 electrical switch does not let you do this, it has an interlock. Once you have hit Start, you have to turn it all the way back to Off before you can hit Start again; cannot simply do it from Run after the first time.
Yeh, I still miss/prefer the old behavior...
