Mag Drive Model Identification Needed

[lilredwuck]

I purchased a mag drive from an individual for $10. It has a broken housing cover. I can not figure out what model I have. There is nothing on the pump. The measurements from what I have and websites are totally different. The box part deminsions are 4.5x4.5x3" Can anyone help with this? I would love to get a part ordered today. The danner mft isn't open until Monday, but I have sent the company an email. Thanks

The outlet part is broke off the housing or the male part is. The female on top is wierd. It has a black piece over the inlet so it can fit the black filter on it. Anyways the inside part from thread to thread is 15/16. The impeller shaft is 4 1/4 long down inside. He confirmed he didn't have the impeller and it is a mag 21. The OD of the female end black piece is 1 7/16". Also I am wondering if the part the power cord runs in, is that a cover? Can it be removed? Don't want to break just in case but it isn't moving and dirty is it just stuck, etc.
Also I just wieghed myself, then myself and the pump. Difference is 7.4 lbs +/- 0.2 I saw a site earlier that had shipping wieghts, but not a clue where it is now.
