Do you mean to the rear end, the C6s that I am familiar with all have slip yokes?

Most all have slip yokes as mentioned.

Are you talking about the square U joint flange?

If you have them use them to size it. If I recall they were Grade 5 or 8 shoulder bolts. The heads were not full height for clearance. Some one with a exploded view may have the specs.
