When Don Yenko installed the Magnum 500 14X7 wheel on the 1970 Deuces,did he use the Bolt on Center cap #3956770,or the later design spring clip cap #3983323?

Actually, neither of those are correct. the part number Yenko ordered was 35859, it was not a GM part number, but rather a MotorWheel part number, as the caps were purchased direct from them rather than through GM. Yenko bought these in complete sets of 4 in a box. He then added his own "Y" center decals over the Magnum 500 logos. Some cars didn't get the Y's originally, and were sold new with caps as shown below.
