CVI automotive sell B2AF for B20A engines made in 1969, B1AN for 1970 engines and B1CC undated.
Scandcar sell B2AF for B20 engines up to 1970
Classic Volvo Restoration in the States sell B1AN for B20A engines 1970-72
I feel like the man with multiple watches who never quite knows what time it is!
All three needles are similar at the wide end but narrower half is different in each case. B1CC is leaner, B1AN is in the middle and B2AF is richer. What I don't know is if the differences are really significant. I've attached some graphs showing the differences - needle diameters at 12 sections, all in inches.
I'm tempted to apply the Goldilocks principle and go for the one in the middle!
