Is this because of the different output shafts on the steeringboxes? I think that the Imps used the large output shaft and the 'regular' Chryslers had a slightly smaller one.

The C-body Chrysler Idler arm is different than the Imperial Idler arm, in other words, you can't just take an Idler arm destined for a Fury, or a Newport and bolt it on Your Imperial, it is NOT the same part. My experience is with the 69-73 Fuselage Imperials, and earlier years may be different, but one thing I am sure of, the C-body idler arm does not fit the 69,70,71,72,73 Imperials.
