I found the same thing a the NAPA store.. Am going to the hot rod shop today. A related question. I had to drill out the retaining pin in the diff. that holds the one spider gear shaft
so that I could pull the axle. any ideas how to replace it ? I sorta planned on tapping the hole to the next bigger size then fabricating a new post/pin. Anyway I could use epoxy to hold the safety pin in instead of tapping the new hole?
