'63 Imperial Crown convertible data plate

[Phil64]

Yesterday I went to see an Imperial 63 convertible to be restored. There is a lot of work, the pot metal parts are all pitted, the engine is disassembled, the fender shields, the radiator, etc. are missing.
I took a pic of the data plate, can someone decipher the options? I already know it's a very first model (08/28), sequence number 0023. Trim 955, red leather & vinyl. The VIN is 9233102465.
What interests me is what is coded in the middle: A2, B2, C3 etc...
Thanks

Sorry for the delay. As a favor to me, please confirm the options and equipment actually on the car, s’il vous plaît.
