My c6 has about 176,000 miles on it and it's acting like it wants to shit the bed. I can get a zf5 out of a donor truck i know of. I tried searching but couldn't find exactly what i needed to know. so, what would i need exactly to bolt the zf5 to my 302 in my '84 bronco? and are any modifications going to have to be made to the body or motor?
