As some of you may know, the cargo coils that I have been recommending for over 20 years for the front of V8 Studebakers have now been discontinued. Moog used up the inventory and will not be reproducing them any longer. Their original application was for 86 - 93 front drive GM cars in the rear.
I made some calls and found a few sets. Rare Parts 1-800-621-2005 has two sets left in stock. They are a different brand but the same spring.
CC653 was intended for a little heavier GM car and it would work in Studebaker applications with high front weight. CC661 is a similar coil but a little shorter. It may need a spacer on top available from SI to work. If you find a retailer with dusty inventory, they still may have some CC655's out there.
Good luck searching
