         They are quite twisty. I tried my best to measure the equivalent 
of the centerline distance. Probably plus or minus an inch.

         They look about an inch and a quarter ID. I didn't measure them, 
however.

         The others are similar in diameter. Perhaps a touch smaller.

         I'll measure the ID tonight.
