Not Ranked
It is my opinion that the top tip of the shaft from the MGB rack needs to be supported by some sort of bearing or bush. The intermediate shaft in this setup does not need support.
The steering column/shaft on the Butler is firmly mounted to the top of footwell on the gas pedal bracket. The other rigid bearing in at the rack and the rack shaft then extends up about two feet and is unsupported. A 9" intermediate shaft completes the connection from the column to the rack with two u-joints. Under heavy steering it may have a propensity to try to straighten out the drive-line and apply leverage stress the rack bearing.
I made a small custom steel bracket that bolts to the Butler frame. It has an aircraft style ball joint that supports the tip of the MGB rack shaft. Supported it perfectly. But after installing the FastCars IFS on my Cobra the support I made for the Butler set-up is no longer needed.
