Hi Bob,

The hardware is being purchased separately. As far as having the parts 
fabricated, are you confirming that we can go forward? Meaning you have 
review the changes and the drawings are now in compliance with your 
previous comments.

We want to make sure these drawings are correct, to eliminate any delay 
due to confusion on the part of the fabricator.

As for the hardware, we asked you for the English standard equivalent 
for grade 10.9 when we purchased the hardware for the Stiffening Tool. 
Your recommendation was grade 8. Should we just buy that grade for these 
parts, since they will be used for the load test.

I will ask Dario to remove the hardware grade, per your suggestion.

Thanks,

Marc
