I put two GMB's in, one in a Contour, one in a Mystique. Got both of them thru NAPA at different times. They sell them under the DuraPro name, but the P/N is same, 125-1910. Both were niceley made, great quality, and fit and worked perfectly.
The gaskets were standard paper (not the rubberized metal type Ford uses), so I used some Permatex aviation sealer on them. No leaks. I removed two Ford types, both with the black plastic impellar, they looked Ok and the cones were tight, but ....who knows at 50K miles+ when they might fracture.
