Great, glad to help.
It's very common to do that, because it does seem intuitive to put it parallel to the ground. But if you look at the original one you're replacing you can see the angle you want to match. Basically with the grease fitting pointing up more towards the bottom of the radiator.
Those with '76 and '77 Broncos don't have that to look at though, as they're converting from a completely different style. So it would be even more important in those cases for us to point it out.
The funny thing is we actually changed the pictures a couple of years ago to better reflect this, but I see from the image above that the #2351 did not benefit much from that change! Luckily the #2390 actually shows more of an angle.
The web pics are just the first line of defense though. However not everyone is going to consult the web pic when doing an install I'm thinking.
Pretty sure we were also going to put a sheet of paper in the box highlighting the angle, but that may not have happened it sounds like.
FYI, the angle is important for two reasons.
One basic reason is that raising the lower end of the draglink actually helps to better put it more closely parallel to the trackbar on most Broncos. At least when the steering linkage is using stock mounting points.
But stock angles or not, the second and just as important reason is that this angle helps to impart less rotational movement to the tie-rod.
If you aim it straight ahead, the initial tendency is to "roll" the tie rod upward when steering left, and downward when steering right. This additional movement before the tie-rod starts moving left or right gives the steering a slightly more vague feel. Keeping that rolling to a minimum is very conducive to a more linear feel.
Ford figured that out. We're just adding more rigidity and adjustability to the mix.

does it need to be pressed in or am I doing something wrong? It seems like a real tight fit almost too big.
