These days even Land Cruisers and Hiluxes have A series diffs even though they are different sizes. Pay no attention to the A . Measure the diameters of the crownwheels and count the splines on the axles if you want to know what size diff you have. Altezza A series have F series size centres . Have a look at the Toyota EPC and try to use that as a guide to what is interchangable.
