Pontiac1976 -- thanks for the pics and info!

The new boot arrived yesterday. It is the correct shape but once again the diameter of the boot's base is smaller than the coupler opening -- so much so that grease would seep out near the areas the boot doesn't cover. The original boot fits snugly in the coupler opening -- no slop whatsoever.

What is the deal? Could my couple have come from a different manufacturer? (ie, not GM original part?)

tommy217xxx, I think this confirms that the Chevelle part will not fit our trucks.

I may need to improvise using one of the incorrectly sized boots.
