I have zero experience with that setup so i can’t say, on my 70 I kept it as to actuate the vacuum doors for the HVAC and the heater control valve. I was able to get away with a tiny notch on my 1st gen dodge mounts but perhaps in your case you could use a stock mid 80s up gm metric line. I’m using the cummins pump with 88-99 lines as they all seem to use the 18mm and 16mm thread connections.
