Well actually Toyota made two different versions of the forward shifting transfercase.
1) 1984 - 1988 22R
2) 1989 - 1995 22R-E
(2) has slightly shorter forward shifting rods as compared to (1)'s rods. So you must swap your (2) rods into your 84 case. The top shift base I was refering to was the transmission base as it is different on the later-W56 (W59) compared to the G52/4 base plate.
I guess I shouldn't have mentioned the word 'top'
