Answer 4

the easiest way to find out for shure is get the vin # off the tranny and search for the trans # to see what it was but that doesnt mean that it hasnt been rebuilt and had the ratios changed.Either way it will probably be fine thats what my dad used in his modified here in texas and it worked good for the short tracks
