[/FONT]I don't think I would be comfortable with the u-joint style coupler posted. Without any method allowing for the coupler to slide up and down it looks like it would cause binding everytime the the u-joint rotated. I would like to see a company make a coupler similar to what modern cars use for their steering intermediate shafts. Here is a link to a picture of what I mean.
And for those that have problems with factory style coupler seals, there was a factory designed bail clamp that was introduced that would clamp the coupler seal down tight and prevent it from coming off.
