You need 2 joints, the box has a 3/4" 30 spline input, the size of the column is double D 1" The only time you need 3 joints is if you have to get around an obstruction
Looking for the EZ Fit steering shaft was difficult. It looks like one of the only places to get it is Flaming River themselves. Even then, their website doesn't list it in steering shaft section. If you do a search for "EZ Fit" it says there are 19 results but nothing to click on or see. The site is a bit wonky and I had no luck ordering (wouldn't take visa or paypal), got an error code both ways.
Luckily there was that article that had the part number. I did a web search using the part # and I got this:

There's a comment section at the end of the order process to put in your specs. I would call if the site still won't take payments.

If I had a jeep shaft I would drill right through it with a 5/16 drill so you don't remove to much material from the steering shaft and use a nut and bolt to secure it. After someone having close call with it I would not trust it.
