Carb Differences

[Murphy]

Is there a difference between a carb on a 68 400 and a carb on a 69 430? I know the numbers are different, but is anything else different :Do No:
Thanks,
Dan :3gears:

68 400 7028242 (auto) 7028243 (manual) Both have 70 jets, 43 rods (auto), 44 rods (manual) BG secondary rods

69 430 7029240 70 jets 45 rods AY secondary rods

I'm sure you could interchange the carbs (assuming in good condition) and never know the difference...
