Truck rear end ?

This will be going in my 65 dart /6. Later on i want to install a turbo. I want to upgrade all the suspension. Being that the 8 3/4 is VERY over priced and you have to rebuild anyway.. Looking at a grand or more when its all said and done.

I'm looking into putting a new rear end from a 02 or newer truck. I can cut the housing down myself. Get the axles splined at a reasonable price.. It will come with gears 3:55's and dics brakes.

Anyone done this??
