Try this trick. Go to car-part.com (search engine of salvage yards). Key in make/model/year and such. If there are sub models, the web site will ask additional questions.
For the 1996 Model year, a search on the gas tank does not ask any additional questions. Conclusion: the gas tank is the same for the V6, SOHC, and DOHC.
When searching on the fuel pump, it asks for the sub model. Conclusion: there is a different fuel pump for the V6, SOHC, and DOHC.
I am not a Cobra expert. I suspect the difference is the higher flow Cobra pumps (just a guess on my part). In any case, there has to be a difference or the salvage yards wouldn't bother tracking it.
