Trucker, I have the manual and parts list for a Barracuda model 8900B. Think that will help? I don't know what the design difference might be but is probably real close. Mine is a year 2000 model auger.
And I think I found a 8903B manual as well. It seems to be paired with a user manual for model 893B and others, but 8903B is noted on the page. I have a pdf file of that ready too.
The augers from all three models all look the same in the pictures.
Send me a Private Message with your e-mail address and I'll send you a scanned copy of the lists.
