55.2-59 Cutting steering column to length

[popeyestruck]

Using to cpp 400 kit and keeping the original column shift column on my 59. Trying to use these instructions but I'm confused. https://www.motortrend.com/how-to/po...traight-axles/ I cant figure out how much to cut off the shaft. If you look at the photos it says he wants to shorten the column 3 inches but then shows a photo of him marking the shaft at 3/4 inch. The rag joint adds about an inch so I would need to remove 1 inch just to get back to stock length . If anyone has done this how much should I remove from the column to get it off my chest but have to gear shift still work?
