My only problem with his answer is that he used a lifter pulled from stock for his subject. If there is still a problem with 40% or 60% of the lifters being assembled wrong, then the only way to be sure of the correct assembly procedure would be the engineering drawing. I asked about a drawing when I talked to the Tech and was told that they didn't have one. So it appears that they don't make the lifters. I would try to find out who makes the lifters and contact them for the proper positioning of the metering plate. That's the only way you are going to be sure that the information you seek is accurate.
