[AT] .40 main bearings allis B

[Doug Tallman]

There is a flip side to this that I haven't seen mentioned. If it 
actually needed .040 to make it round and clean then the crank was just 
plain junk from the get go! Any way you sliced it, you would have still 
had a crank that wasn't usable. Yes, the machinist should have told you 
that it wouldn't work but as far as buying you a new crank?????? Who 
knows at this point! Doug T
