9-1/4 rear end problem
Rumble,
These are real easy rears to deal with since they're the c-clip style. Pull the drums and diff cover. Remove the locking bolt that holds the spider gear shaft on. Remove the spider gear shaft. Push the axles in and remove the c-clips with a magnet then pull the axles straight out. Make sure you have enough room in the garage to get the axles out from both sides or you'll be putting the whole thing back together again and re-positioning the car.
PM me if you want an exploded diagram, I should be able to scan one.
Good luck!
Oh yeah, it's easier to get the pinion shaft nut off BEFORE you jack the car up LOL! A 1/2 or 3/4 impact gun should spin it right off.
