Differential drain plug

[Snakester]

Right now I've got the differential out and I'm about to have the stock gears swapped out for 3.55 gears.

My mechanic commented on the fact that there is only a fill hole on the differential, and maybe the guys putting in the gears could tap in a drain plug for draining the fluids.
Is this wise, or even needed.

Also for you guys who have done this. Are you supposed to use regular fluids with the limited slip additive, run it for 500 miles and then swap out the fluids?
Am I supposed to baby it for that time or just drive it normally?
Plus 500 miles will potentially take a while on the Viper.

Any recommendations on gear oil brands (synthetic?).

I put a drain plug in because the fluid is so thick -
it would be hard to siphon out completely. It's simple to
do - see illustrated updates. Always use synthetic - but drive easy for 500 miles(then change fluid) - no long trips or hard driving. As long as the weight is right -
and it contains the friction modifier(add it if it don't)
also make sure it's fully synthetic.

Looks great! Thanks for the tips guys.

The rear end guys wanted $60 to drill and install a plug, which I thought was out of line for 10 minutes work and a $2 part.
So my mechanic is going to do it.

Well, we got the differential drain plug installed, and everything is back into the car again. There is a little gear whine, but not bad, but I'll have to see how it goes when I get some break-in miles on it. It doesn't feel much different, but I'm not driving it hard for a while.

Thanks again everyone for the info and tips.
