Power disc conversion 70 charger

[charger_fan_4ever]

My 70 rt was manual drum brake and automatic.

Im changing itnover to 4 speed and power disc brake. I used the below brake kit. Wondering which firewall bracket i need to buy? Insee there are 66-9 firewall booster bracker and 70-74 style. Roosevelt mopars sells both. I have googled 70 charger pucs and see some with 66-9 style bracket.

My kit doesnt say what the booster is. Wondering which firewall bracket i need. Ideas?

Thanks

It works well you will be happy! Install the restriction to the rear drums and adjust.
