Hope this is helpful.

I know this is super old, however I'm putting my front end together. I get the fact that they should be towards the front and slightly towards centre, however, what does the notch index into? The Moog instructions say there should be a tang. I see nothing.

Re: A-arm shaft?

If I recall correctly, in the middle of one of the saddles where the lower shaft rests there should be an indexing head that fits into the dimple of the shaft. On mine I think it looked like an oversided rivet head. You can sortof see it in the picture on this page:

Hope this helps,

Re: A-arm shaft?

I just did mine and jonmc56 is correct. The rivet in the front saddle is your index pin. I broke my old bushings loose while on the truck with a big wrench where the arm would be solid enough to really get some torque on it. Then after it was off put the arm in the vise and finished removing the bushings. When I installed the new shafts and bushings I put my seals on the shafts first then put grease on the shaft threads and the A arm where the bushings go in. inserted the shaft into the A arm them started the bushings hand tight until the bushings started into the A arm on both sides. Turn them in about another turn then check to make sure the shaft is centered in the A arm. I check this by measuring the hole in the top shaft to the outside of the A arm and turn the shaft one way or another to center in the A arm. The same way for the lower but I measure off of the shoulder of the shaft to the outside where the bushing goes in. This was my first install and it is a little intimidating in the beginning but its not that bad.

Awesome! Found the pin, didn't realize it was in the saddle. Thanks so much!
