You need to take the Toyota e-locker gasket, trace the cutouts onto your housing and clearance it. You need the short-side axle shaft with longer splines. The correct part is from a full-floater with a cable locker. It's probably available from Toyota. You also need a couple of studs that are longer. There are threads around here. I like to use google to search and add "site:ih8mud" to the end of the search line to only search here.
