90 Ex Oil Cooler?

[blageo23]

Does anyone know what the thread size is for the cooling lines for a 1990 External oil cooler? Im going to be running -8 line to my new cooler and want to start ordering some fitting for it(I do not have the oil filter housing yet). Any help would be great!
Thanks,
Mike
