Mine was installed end for end when I put it back together. This [/b][/i]was[i][b] on an 83 D150, and that's not your model so things may be somewhat different. I could see the difference when they were side by side, (correct vs incorrect), so I took mine out and end for ended it back in - and all was well with the world. I had the front end apart for several months doing the rebuild so that's my excuse - took me too long so I forgetted........ As I recall, (this find was around 5 years ago now), the giveaway was the stud/nut orientation of the tie rods/idler/pitman; correct they angled aft and down and incorrect they angled fwd and down - or vice versa.
