The last number definitely IS a "2" (trust my 20/20 vision from laser eye surgery ) I have the pump in my hand and it IS the GSL 392. I would post pics if I had a digicam. Good company to do business with, quick shipping. I also got the install kit with it. Great price, quick shipping. Thank you to "The MATRIX" for posting that find! I'll post my install results on my day off tomorrow in the proper forum. Â - Justin
