I am wanting to lower my 85 Ram 150 and I have the opportunity to pull the LCA's from an 80's Dodge van and am curious to a few things. Are there any other parts I need from the van? There are two vans there, one is a 3/4 ton and the other a half ton. Will either work and is there an advantage to having 3/4 ones such as larger ball joint, more heavy duty, or any other reason? Is it for the most part, a direct bolt on?

Thank you for any info.
