I have a 91 d350 also and i rebuilt my whole front end last summer. The parts a got were "moog" as well but they were the cheaper ones. I think mine were around 20 bucks apace also. Long story short, I a about to rebuild it again because the bass joints have already worn out. If you can move the joints with your hands, there too loose. Hopefully yours fairs better.

 

Man I sure hope so.

 

Ain't that the truth.....

 

Ya. I'm re-doing mine with the expensive moog ones this weekend. I'll let you know how they turn out and if it fixes my problem.
