There is a spec in the manual about a dimension. I'm hazy on the details, so it you have that manual, I'd recommend looking into it for that dimension. I did this a couple of years ago. Looks like you asked the question at the right time, since your suspension is easily accessible. I did mine in the driveway, under the truck. Talk about grease and dirt. The parts were original from 1970! I think that the truck rides a little higher in the front after the removal of it all.
