Not Sprints, but I thought I'd follow up on Marlins pic..
Here is the 4-3/4" 14x7 Dragmaster for comparison. They did not use a bolt on center cap. Not even sure what the correct cap would look like. I've had these for close to 30 years. When I first got them they had Bluestreak slicks on them & came off a west coast 57. Very light rims...
