The center vertical duct is actually the same part all the way up to 1987/91. It is part number 6262679 DUCT ASM, Air Ctr Lower:
The LH outlet duct looks the same, but it has a slightly different bend at the end - I think. But it's probably nothing that couldn't be straightened out with a little help from a heat gun.
See Note #1 - apparently the 1973 model year doesn't use a lower heater outlet diffuser. Back in '73, when men were still men...they didn't need no stinking floor heaters!
