Sams,
This thread is timely.  Originally, I called Carver for a toothbar. They called back quickly and wanted me to measure the inside of my bucket.  But I remembered a thread here that suggested the bucket lip measurement was equally important. 
I was concerned that lip size didn't appear to be an issue. So, I then called John Millers' boys (Mark at K.C. Canary-Fultonville, Inc.) and they knew my bucket and said they'd measure it for me. 
I received my bar on valentines day, 6 days after ordering. I just test mounted it yesterday afternoon.  I used a big hammer to get the tooth bar on and it is so solidly mounted, because of the lip "fit", I think I could actually do things without bolts! It fits my bucket lip perfectly, but the inner bold mounts have about 1/2 inch play. I'll shim this in with some extra washers. 
I paid 260.00 and 14.90 shipping.
