Factory BBP on 7.25 axle

Here is another tidbit of information you might find interesting.

This is a TSB on the 73 A-bodies showing the front end and the rear end has different widths. It states the front end was widened another 1.6" for a total of 3.6" wider than the rear. Would this be the case on the earlier cars also?

I believe all A-bodies had wider front track than rear track -- the exact amount changed over the years. Apparently, by 1973 it had become noticeable to the average joe on the street, hence the bulletin.
