LS3 swap (replace LS1, kept accessories) in my Genesis, F-body accessory brackets (dirty dingo) since it fit the best, BUT my standalone harness has a 2 pin alternator, so I cannot use my 4pin Fbody alternator. Will a GTO 2 pin alternator (P/N 92211821) physically fit the Fbody alternator bracket? I cannot find any info after searching.

No I don't want to rewire the harness, or the voltage regulator.
