Its been said that one axle and tube is longer than the other in those Ford rears. If that is true and you welded perches equal distance from the center, wouldn't one tire sit farther out from under the car ?
I read somewhere that a guy bought parts needed to install the shorther axle and tube in both sides of that rear and it fit the A-body perfectly.
I couldn't post to this thread when the guy asked for experience with this swap because I have none.
Opinions on using a Ford rear isn't what he asked for and I didnt have one of those anyway.
