steering coupler replacement (how to)

Are you trying to stick to the factory setup? I switched to something like this and it works great!

Hey there MERIDIAN. So I noticed this is about a decades old thread but thought I'd give you a holler and hopefully it reaches you. With this universal u joint set up you installed on your steering shaft did you get more or notice an increase in vibration on your steering wheel?
