Well when I let the vo tech first years finish my year end swap since i had to go to class i noticed my leaf spring centerin bolts are no in...It took me 3 months to notice this but after getting under the truck to look why the outside of one tire and the inside of the other are wearing so bad i found my problem...the axle shifted about a inch to one side and got kicked the the right...I really need some help finding the part numbers for these. Autozone and them jus looked at me like i was stupid when i asked did they have them...someone help me out with a part number or a link to where i can get 2

 

I think they are 10mmx75mm allen head bolts or something close to that and can be picked up at just about anywhere that carries nuts and bolts.

 

thanks man
