A283 is a date code. January 28, 1973 or 1983. The older 465s have the bottom two bolts that hold the tranny to the bellhousing coming in from inside the bellhousing (threaded holes in the tranny), while later models have all four bolts coming in from the tranny side. Early model 465s ('68 - '72 era) will have a second electrical switch on the tranny (besides the backup light switch) to indicate that the tranny is in high gear for the TCS system.
