K-car brake booster question

Hey everyone,

So I’m trying to install Mopar Performance aluminum valve covers on my 318, and they hit the brake booster. I’m pretty sure I read that a K-car booster will bolt up with some modifications to where the petal connects. But I just wanted to make sure that the bolt pattern is the same for the firewall and the master cylinder as the stock fifth avenue booster. Thanks in advance.
