I have a 8 inch rear end in my 65 stang. it currently has 3.55 gears, But first of all i was wondering if someone could tell me the main difference between a 8 inch and a 8.8 inch rearend? Bc the rear end we have, came with the car when we bought it 5 years ago,and have had engine, tranny, front end, and interior all redone ourselves. But we dont know for sure if it is a 8 inch or 8.8. So is there a way to figure out which one it is? Now to the main part, is there a certain year of the explorer that you can buy from a junk yard that can just bolt up, and just have to relocate the spring perches? We want 3.73 with Trac Lok, but i also rear you have to shorten the axles. We will stay with rear drum brakes bc it has all been rerouted already. But would this be wise to do, or just buy 373 gears and a detroit trutrac? Any advice is needed. thanks
