Am trying to find out what size jets are required for a CARTER 3720SB 4 barrel carb. I need the sizes for the proper main and secondary jets. The originals were mutilated and can’t read any numbers. When I go up on EBay it asks for numbers such as: .087, 093, etc. the carb was,originally installed on a 64 Vette 327/300hp with a power glide trans. Any info appreciated. Jerry
