hi,
i'm trying to figure out what parts do i need to install a itr 4.78 final drive in my y21 tranny, but i'm from Portugal and the dates and codes of trannys are slighty different than yours.
I know i have a y21 tranny and i'd like to know the parts needed to install the 4.78 itr final drive in my tranny.
