motor mount problems in my 67

my motor in my 75 is really close to the firewall. I bet I only have 1/4 in at the furthest spot from the motor. I actually have a bolt that is rubbing on the plastic intake. (gotta pull the bolt and chop it down a little it holds the heater box in under the dash) although my engine oil pan apears to be flat in the car. So you might have something going on there.
