Hey all. 75 Monte Carlo. Replacing the brake booster and resivoir. Tore it all down today and realized that there is a bracket between the booster and the firewall. I'm seeing on Summit Racing there's a bunch and nothing specific for the 75 Monte though. You can see in the attached pics that the bolt pattern on the firewall is close together on the one side than the other. The new booster is a 9". Looking at THESE
but seems like the holes aren't even close. Any ideas? Thanks!
