New leafs too high, how much will they settle?

Fat is where its at or so they say...:)
Put them both in the back seat on opposite sides. I had Dave Barnard and Geno Schaumburg on the same side in a 68 Coronet R/T I had years ago one in front and one in back and it looked like I had a broken spring on the passenger side. I had to ask Geno to sit behind me instead of behind Dave to even out the load...LOL Two incredibly stout gentlemen!
