Mmm, no. Nothing to get over. Facts are facts.

Every one of them Ive ever seen had the normal size front brakes. Even the ordering books from Chrysler only anyhing about the back. Id almost guess some agency had older parts around and swapped them on but who knows.

The bigger drums disappeared in 1988.

I guess I'll have to carry half of the Moparts crowd in my back pocket next time I go to the yards to pull parts.

I've got nothing to gain by telling tall tales concerning parts pulled off cars nearly 20 years ago. I must have been lucky more than once with the exact same parts on the same kind of cars.
Maybe it was a local department thing. I dunno. I went looking for white M bodies. Very few of them had what I wanted but I did find and pull the parts myself.

Fact your little heart away. I really don't care.
