On the 521, the steering column goes straight into the steering box. When I bd mine, I plan on swapping to a later model steering box with a standard input, then use a flaming river or similar column.
This will have the added bonus of some semblance of safety, too- right now, your steering shaft is a solid, spear-shaped metal rod that goes from 12" behind your bumper to 12" in front of your chest plate- not too safe in a collision!!
Newer columns have a failure point built in so it will collapse if you get in a wreck, saving you from impalement!
Good luck with your project!
