Rear Diff. drain Plug Install.
Most of you may already know about this kit from the Corvette Clinic in Sanford, FL, however I just installed on my '90 yesterday and was wasn't a bad job at all. If anyone is looking for an alternative to dropping the entire rear suspension out of your car to change the diff. fluid then this is the answer. I think it's www.corvetteclinic.com, they are $55 a kit.
Behave yourselves,

Not that a drain plug wouldn't make it easier, but it's not very difficult stock.

Suction pump, Cracked Diff
A vacumn suction pump will take every last drop of diff fluid out with very little effort. 40 bucks tops and usefull for other duties. DONT drill the hole. I have seen 2 of the installed rear drain plugs crack the housing under pressure. Anytime you make a hole where one doesn't belong you are asking for trouble. Now I know and have seen many done with no problems as of yet one would have to ask why you would want a drain hole anyway. Even if you drained it every 10,000 miles still wouldn't be worth the chance. Take a look at how much those Dana 44 go for as you are tapping the hole. ....G

Is there a an inspection access plate that you can remove easily without pulling anything on the back of the danas--like regular differentials do. i would like to be able to pull the plate and either clean the magnet that picks up metal shavings, or put one in. getting out the last of the oil and wiping down the inside of the case is wonderful.
or doesn't the dana have one to give integrity to the aluminum housing?

The kit comes with a template, very easy to lay out and drill. The apprehension of shavings left in the diff is not a concern seeing as how the gear oil will take the shavings with it as it drains. Aluminum is a relatively soft metal and doesn't crack under that type of stress, and if you tighten it to the point of enlarging the hole, you shouldn't be working on cars in the first place.

FYI - To get one of those pumps to evacuate fluid, it is free at autoZone, just leave a deposit. 
Have used it on transismissions, it was great. 
Pulled my fluid about 8 or 9 times before I changed the filter in the vett. Why, it was real nasty and took that long till it got clear. Then changed the oil another 3 times. Used it on my other cars also.
