All you have to do is match up the numbers. All of the variations each have different numbering. Some of the parts can be interchanged but some of the springs and metering elements are varied for different flow rates of air and fuel. This is just another case of "If it fits it must be OK". NOT!!!! If you get your parts from a Delorean vender even though you may pay a little more you only buy 1 and it is the correct one! It is rare that you would need a metering unit anyway unless of course you don't have the right one.
