Sta Lube (?) At NAPA is the only GL-4 lube I have found on the shelf. Stay away from any that say GL-4 & GL-5 compatable, they are Gl-5 oil, admittedly a better high pressure gear lube, but hard on synchros. There has been lively debate here about this, but Mitsu directly specifies GL-4 for the x-fer case with GL-5 for the diffs, must be for a reason.
