*Note: This is a general rule to follow, but may not always be true. Sometimes no bosses are machined.
Look for machined-down boss (A, B, C or D) on the upper casting. Generally, if the A boss is machined down, this indicates an MYA/6L45 (see chart above). This identification system is not foolproof, as some valve bodies do not have any bosses machined down.
