My 1980 4x pickup shifter has a bolt on the bottom in a housing that connects to the side shaft. This bolt has 2 thread sizes -- kind of a "step-down" look. I need a new one and toyota dealer ordered 2 incorrect parts so far. Now they say the part number does not exist. I have a diagram that shows the bushing, boot, housing that matches my set up with a bolt # 33521 F for housing 33521 mating to shaft 33203. If this makes sense to anyone please let me know! Where in the world can I get one.
