My way is easier than that but i hatw typinga fine point black sharpie and a machinist ruler can do better than that.
twist the shock body at 45* angle with the cap already halfway on. put the bladder inside the cap first. make sure you have the shock shaft exposed for how much rebound you want. no rebound. no shaft. "emulsion" style shock. for oval.. good luck. each shock will be setup different!
