In the old days of cable driven speedometers, there were mechanical adapter boxes that fit between the transmission and the cable. Local International Harvester dealers parts depts were always good source...if they didn't have the ratio you wanted, they could get it for you. Their trucks must have used those, because I could always find one close to what I needed there. More often I'd scrounge the wrecked scouts in the local parts yard to get them cheaper. I don't know what they use now that speedometers no longer have cables...and confess I haven't looked... I'd suspect that the ones IH used were SAE while the Subarus likely have metric fittings?
