Sure grip and gear install

get yourself a Chrysler service manual for your car or any other mopar from the 60' s and read the section on differentials -- then read it 10 more times till you understand it --- have the book nearby when you take apart your diff and go section by section ---- forget the Richmond dvd it's USELESS -- you can do it but take your time and pay attention to the details and ask questions here if unsure ,, the internet has really muddied the waters on most things.
