what ball joints for mcgaughys 2.5" drop spindles for 63-70 #63173

[littlevictories]

Hey Folks,

I'm still trying to make this thing ride right. 2.5" drop, LCA modded for 6* positive caster. I replaced the wear parts in the front end last year and I think I used the wrong balljoints. Everywhere I have read says the #63173 spindles use the stock (in my case 1966 1/2 ton) ball joints. And that is what is in there now. Today I called McGaughys (now switch) and the tech said the 63173 uses the '73-79 ball joints.

My problem is that the stock balljoints for my year leave about 1/4" between the top of the castle nut and cotter pin hole. They kept loosening up, so I kludged some washers under the castle nut so the cotter pin would engage.

It's still not right and I'd like to make this work. It's gonna be some time before I can afford a porterbuilt or the like. Trying to buy a house so funtime funds are really tight.

Any help is appreciated. I've searched for an answer multiple times and it seems like most people are using the stock for their year ball joints. Did they change at all over the years (im stricktly speaking of half tons here)?

Thanks folks


Doug
