I have a pair that came from a 67 with a 273 numbers 2465 769 and 2780 845, if your interested. They were used on a 75 360 for a short time before headers were installed.
I have a plan but I feel I need to provide the shop with parts requested. I need him to fix the intake manifold oil leak. I can convert to manual brakes myself. I realize it's my car but I took the car to him needing his help.
