the L43 is the first 4wd tranny toyota had. its the exact same bolt patterns as the later Lseries 5 speeds but they are much lighter and have a 3.64 1st gear where as the 5 speeds have a 3.93 1st gear.
you WILL NEED the L43 shifter because the L52 has a different shifter
here is a picture of the L43
and here is a picture of the L52
