Ok this is getting weirder.
Radiator Barn is telling me that:
1988 LandCruisers use the same radiators as 1981-1987s do AND
1989 LandCruisers use the same radiators as 1990-1992s do
THIS MAKES NO SENSE.....
A friend is finding out directly from CSF today. I might have to pay the extra money for a Performance one since they at least list the same Radiator for 88s and 89s.
