Hy glasman, so the 2687/2631 did fit okay, but the 3383/3320 didn't? I checked the Napa site this morning, and the picture of the cone shows it sitting up off of the table so I hope that means it has the seal surface on the back of it. The napa numbers for those bearings are BRGBR17888 $67.99, and BRGBR17830 $19.69. The 17888 has an I.D. of 1.75", and the 17830 has an O.D. of 3.125", do those dimensions sound correct?
