.89 on the old gears, and .88 on the new in 4th

Only 3rd and 4th went to the finer teath. And I don't think that a T-3
owner would notice the difference, due to the better sound deadener. In
a T-1 111 plain jane, you could definitely tell the difference. 
One thing we found with the finer gears, was that it was best NOT to
pull a trailer with these gears. We had several come in under warranty,
with teeth gone off of 4th gear, and it happened while they were pulling
a trailer.
