Yeah,Idid
Idid the 44 swap on the TTB a couple years ago. The first thing I noticed is the brakes don't feel good. As far as the actual bolt up, the balljoints are different where they go in the steering knuckle. Ex's were smaller outer diameter. I took a piece of steel (not sure the thickness now) and cut strips to fit around the outside of the balljoint from the Ex, then fitted them into the hole in the 44 knuckle and spot welded them in place. You'l want to make the strips narrow enough they don't cover the lockring groove in the 'joint. Then I used a wheel cylinder hone and honed the shims out until the Ex 'joints were about the same press in fit as in the original knuckles. This set-up worked well and didn't get loose over time.Another thing I did was the lower joint rubbed the u-joint after assembly making a clicking noise. I removed the hub,spindle and axle, ground the top of the balljoint down to the nut and reassembled it. No more contact. As far as finished mods, it got rid of that front end shake and seemed to handle better,but the brakes were odd feeling due to the larger caliper on the smaller Ex master cylinder. Alignment and front to rear track was unaffected and I got a set of locking hubs to boot. I bought a whole rolling F-150 chassis for 200$ and swapped everything from that. You'll need all parts fromm the ball joint out including the axle stub. the Ex's tie rod ends fit the 44 steering and the u-joints were the same dimensions and fit the same. I would put a F-150 master cylinder on if I did this mod again.
