Well there are some that want the best of both worlds. The way i look at it is if you have a case that matches the engine and has the right part # but performs much better than the stock one why not? As for starters i found a old amature lathe and amature growler(a test for proper continuity) soi might offer a service for those that want the older units that match but rebuilt to new specs. I have to have something to do after i get back from my next deployment. Daren
