I'm going to try to cut out of work tomorrow and head to a swap meet as the newbie that I am. I hope to find an 8 inch rear for a 66 coupe. Any things I should look for they don't tell you in the books? I understand the rear bearings are difficult or expensive to replace? Any way to tell if they are bad? Are tag numbers useful? This is for a driver to work and not sitting behind a powerhouse (maybe someday...). Thanks.
