Blues appear to be 17059595 CXK and 17059596 CXL but it is possible it is off an auto blue 4.2.

Carbs are basically the same between 4.2 and 5.0 except for (from memory) the primary metering rods, you shouldn't have any dramas getting 5.0L rods. Get the code off the rods and give it to me and i'll look up what you have. The difference between auto and manual is the manual only has a ported vaccuum port for vacuum advance, auto carb has a full vacuum port so you can use an auto carb on a manual car but not vice versa, so you are OK as the carb you have is an auto carb.
