Which GM HEI Module ?


Recommended Posts

I lost the box that my GM HEI module was in, and I forgot to make a record of what I had.  My docs say to use a Wells model #DR100 4-pin GM HEI module.  Would someone please give some examples of which vehicles had the generic DR100 module?  Those kids in the AP stores only know "Make, Model, and Year" to put into a computer.  You can't even get a quart of 15W-30 oil for a lawn mower...
