Chassis VIN
I started by decoding the chassis VIN by visiting this site: http://www.buickgod.com/article/3625.html
My Chassis VIN: 494475h907554
- 49447 – Buick Riviera 2 dr. Hardtop Coupe
- 5 – 1965
- h – Flint, MI
- 907554 – Production Number
Then took a look at the body plate which is on the firewall driver side: https://rivowners.org/features/Ev_Stats/colortrim/options.html

Engine Serial
![](https://65riviera.com/wp-content/uploads/2020/02/IMG_4015-768x1024.jpeg)
The engine has a serial number: 8J4008768 which would correspond to the chassis VIN. So obviously engine is not numbers matching with chassis VIN. Also first clue here is it starts with an “8” which means it does not come from a 1965.
I had to go here: https://www.teambuick.com/reference/us_35-76.php
8J4008768
- 8 – Series number – Limited (700), or Electra 225 (4800)
- J – Year – 1963
- 4 – Assembly Plant – Kansas City
- 008768 – Sequential production number, starting at 001001 at each plant, so guessing its the 7,767 built at Kansas
Block Ident

Now the engine ident number: https://www.teambuick.com/reference/ident_engine_63-75.php
JT 362
- JT – 1963 V-8 401 4bbl
Transmission
There is a tag on the passenger side of the transmission, I was able to get to it lying on the ground with my phone. Looked up here: https://www.teambuick.com/reference/auto_400_codes.php
![](https://65riviera.com/wp-content/uploads/2020/02/transmission-tag-768x1024.jpg)
Its BR65 indicating its previously attached to a 1965 401 V8 Riviera (3.23 axle)
Conclusion
The chassis is in fact a 1965 Buick Riviera (duh, look at the headlights) built in Flint, MI painted and with a new interior, with a 401ci Nailhead pulled from a 1963 Buick Electra 225 and a transmission from a 65.
