Thanks for the response. I was going to buy and replace one at a time if I bought new ones, but if they're a bit longer that may not be a good idea.

I heard they were longer but it doesn't change anything that drastically. I was hoping to get used ones, but buying used they could be getting ready to rust out in a year or two anyway.

So besides jacking the truck up, using jackstands and the bolt issue, anything else I should know?
