520 wagon? thought they were utes? 510 wagon? the s13 gear boxes are longer than the normal bluebird,r31 onward skyline,navara type and will move your shifter way back considering the standard 1600 box like the r30 stumpy 5spd is shorter than bluebird,skyline etc.

locally ka24e rwd came in navara d21 and d22 and ka24de in later d22 so those boxes will work as well as z series boxes like z22 found in later 720 utes and z20/24 found in d21 navaras.

is your diff a h190?
