Putting a 3 inch body lift on my 99 silverado and my new bolts to go through the space blocks under the cab wont go in. Any ideas?

 

The holes lined up? Sometimes they can be a pain to do so. If they are, then the bolt is bein stubborn like it was on mine. We could get it to go in a couple turns and then nothin. Hit it with an impact and took 5 minutes after that to finish it up

 

Thanks for the reply but there was little white plastic pieces in the holes blocking the bolt. I just tore them out and they went right in.
