There is something seriously wrong with part #67787. The right side holes, do not match up to the left. The holes drilled for the right side, jam the auger into the housing. I had to center it the best I could and re-drill new holes(a good half inch off). The housing I have is not bent in any shape or form, the only reason I can find, is because your template is wrong. Now, the augers are crooked and have too many holes drilled. Other problem with this part# is, the forty something inch shaft, with key way, has the holes for the sheer pins, drilled off center(about an eighth inch difference).
Next part# with issues is 711-0459. I ordered 4, one of them was about a sixteenth inch smaller(I.D.) and got the luxury of filing it out until it fit.
Next issue - I was notified through email, I would receive my parts in 2 shipments, I ended up getting 3 shipments and never received a tracking # for the third.
Needless to say, I'm throughly annoyed with this company and it's parts.
