Disc Brake Master Swap & P valve Question

Considering the number of out right mistakes I see in every issue of Mopar Action and Mopar Muscle I wouldn't put much stock in statements like that from them.

I know my 30+ years working on cars, rebuilt MC's have never been an issue and do not support a statement like that.

I know when I go to the parts store and have the choice between new and rebuilt, I will take a rebuilt everytime just because they come with a much better warranty.
