Ok. What's the trick here. I got the Pro-M meter with the flange and I'm trying to install it on my car using the stock airbox. Unfortunately it appears that the Pro-M is longer than the stock MAF and I can't get the thing to fit.

How do I install the meter? Are there any tips or tricks to use the meter with the stock airbox? I even had to trim down a plastic tab of the plastic piece that hold the MAF screen in order to get the Pro-M to fit flush against it.
Has anyone else gone through this? Is it possible that they sent the wrong meter?
