Steering column

[voucht]

Hi,
Regarding my steering column extension, I would like to come back on what I plan to do: as I have the lower UJ from the Escort rack, ans the upper UJ from the Sierra column, I would like to put a splined shaft between the 2 UJ's (see previous posts on this thread). This will avoid the delicate welding of the steering column extension

My question is : as there will be two UJ's, so 2 articulations on the column, do I have to link the shaft between the two UJ's to the chassis on a fixed point (with a bearing), or will it work without doing this?
Thank you.
