exterior light bulb question

[bigblock73]

Can someone confirm or deny these light bulb part numbers for my 1973?

sidemarkers #194
front park lights #1157
brake/tail lights #1157
rear side markers #97
backup lights #199 or #1156

I am kind of questioning the tail light part number as well as the backup lights. The tail light bulbs are push and twist type, but have a fairly small bulb. The backup lights are listed as 199, but nobody carries them. The sockets look identical to the sidemarkers...would the bulbs be the same, or are they different wattage?

I would look at my 77, but it is in storage for the winter...and all the bulbs were removed from my 73 harness when I took it apart 8 years ago.

Thanks in advance!
