Inliners International Forums General Discussion Drive Train I want to change the rear diff in my Maverick, any recomendations?

Hi, I have a 1970 Ford Maverick with a I6 200 C-4 trans. I would like to change the stock 2.79:1 rear diff to something else, has anyone else changed the rear diff on one of these, I occastionally go on the interstate at 75 so it cant be revving to high at 75.

Thanks,
RudyD
