Hi Nick
The part number on the site was incorrectly listed. i have corrected the part number given in the description but the correct part will not show on the site for a few days yet. The G/296-2045-1-30 is the same cost as the G/296-2033-1-30. and is in stock in our main warehouse. The only difference between the two kits are the seal retainer plates that go on the axle shaft have a spacer ring that make up the difference in the thickness in the backing plate. if you are installing your disc kit at the same ti,me you already have the correct retainer plates. Thank You
