This is a service replacement carb without a box. This is my first post on this forum. I owned a 1972 Hurst Olds years ago. This carb has been in dry storage for 30 years. I just found it last week, it needs to be on someone’s 72-74 olds. I can post the numbers and photos, when I get home Sunday evening. Greg, five one zero 323 587six text for photos or I’ll post them here.
