1970 bonneville / catalina headers
I ended up going with the 2.5in Long Branch Factory headers Repop from ram air restorations. The fit was perfect. 2 things I had to change up were starter installation and tranny cooling lines. The long branches drop right on the cooling lines as they pass over the frame piece under the motor. and I had to wire the starter up while the engine was hanging over the car for space and maneuverability. I would have liked it if the company had mounting hardware in the package, due to the different length studs needed. I just hope I never have starter problems, could make for a long day...
