Another early a header question

What do the truclk/van couplers look like?



supposed to be longer than the car model and that makes it able to extend the auto column to manual length and reach the manual steering box. I never used them but a few people say they work as well as the >$150 flaming river chunk of steel. Or you can buy a manual steering shaft like I did or even weld one up like I did originally before I ran into a manual shaft for next to nothing..shipped!
