Good stuff, that wheel date aligns perfectly with your SPD, engine stamp also looks legit. The trans stamp is likely a bad try bouncing attempt, the LA plant workers seemed to have more issues with transmission stamping than other plants, I've seen a bunch like yours in recent years.

If you feel like investigating and sharing further here are some more date codes I'd like to see/know.

1. Jack mechanism (one of the rivots holding it together will have a two digit code)
2. Hood latch release mechanism (date code is stamped into the verticle face)
3. Wiper motor (stamped into the gold colored metal barrel housing)
4. Radiator (digits are stamped into the passenger side mounting flange about 1/3 way down from the top)
5. Intake manifold casting date
6. Exhaust manifold casting dates
7. Steering box casting date
8. K-member stamp date (located in the very front center verticle surface, often shallow and hard to read)
9. Lower control arm dates (numbers stamped into two forward facing rivot heads on each)
10. Water pump housing casting date
11. Bell housing casting date
12. Temperature sending unit date (2 digit code stamped in tiny digits on the side)
13. Oil sending unit (2 digit code stamped in tiny digits on the side)
14. Date codes on the side view mirror glass
