Cornfused

I will be tearing into the project in the next two weeks. I will measure old before I buy new, was just a little curious when I went window shopping for parts that new front 9 inch drums called for 2 1/2 inch linings. Did you know you can run 2 inch linings on the front and it will work, just not so pretty-good. I have been doin' it for years and wondering 'where is the whoa', and replacing the hell out of linings. Thanks to all who took their time to help an old man get un-confused !
