The guy to call is Tom Karkiewicz in South Bend,IN, 219-287-5834 he literally has BARNS full of 50's & 60's Studebaker parts from 100's of cars he has dismantled.
He has always been able to come up with the odd item I needed and couldn't find. You have to visit his farm once just to see the scale of how much Studebaker stuff he has. Stude8
