7 1/4 to 83/4 swap - A Body

The only reason I'm going to contradict the gentleman that said you'll need to shorten your driveshaft is because I just walked in the door from putting brakes on my 8 3/4 rear that came out of a 70 Dart and am about to install in 69 Barracuda. If you have access to the Direct Connection chassis book it will explain in great detail what you need to do. But I know the 7 1/4 third member extends forward at the yoke than does the 8 3/4 so you'll need to have a driveshaft made that will be roughly 2-3 in. longer. As far as wheels they should be the same.
