What is the difference between this booster assembly for 58-70 Chevy and 916641331 for 55-57 Chevy? All specs look the same. Is it just the mounting brackets? I have plans for using this in a 53 Dodge Pickup street rod with new Ford 9 inch and GM rotors and calipers. It seems less expensive than most of the universal chrome boosters. Thanks
