Thanks. Leveling from an actual measurement perspective isn’t necessarily my goal. Evening out the wheelwell gap front-to-rear is. Rear ends always sit lower, at least for every car I’ve ever owned, so going with your 56/74 prob is the right answer since there’s a 5/8” difference for me already front/rear if I decide to go for it.Note, in order for me to keep level front to back, I had to use 56 front and 74 rear. 76 rear was about 1/2" lower than the front.
And then I reprinted the 72 rear and oversized it to 1030 (3% larger) because the ball was too tight in the holder. 3% larger was JUST perfect and makes 72 EXACTLY the same length as 74.
