The generator doesn't know what name it has- - - - -as long as the specifications are right, it should work. It's not uncommon for a generic rebuilt unit to cross over several OEM applications. No problem with a generator, and usually generic regulators are OK, but beware of "one size fits most" carburetors! It seems that Delco changed numbers for the same basic unit from year to year, possibly as a method of monitoring warranty coverage, slight production run differences, etc.
