[Dave at Pelican Parts]

When I checked some 73-74 injectors and 75-76 injectors, they *seemed* to have the same resistance (at least pretty close) through the windings. The guy who cleaned and checked the injectors told me that they all flowed the same amount as well. However, he was very careful to separate them out by part number.

If I remember correctly, "Filko" (makes electrical bits) sells just one part number for all the 2.0 914s, 73-76. Bosch however does have the separate numbers.

In other words, I haven't the foggiest idea what exactly the difference is.

Sorry if this isn't much help.
