Manual Drive shaft with auto rear diff?
 

Can you make the auto Companion flange work with the manual drive shaft? I think I read somewhere on here you can drill a new set of holes in it. Anyone tried anything like this? The auto driveshaft is 12mm longer maybe an aluminum spacer would do the trick?

bump. :)

See here for the 5/25/01 entry (about 1/3 down the page)

Thanks, ;)

yes but where would you buy such a thing, he posted no useable measurements...

Ok, from personal experience, ~5K miles, and numerous hard launches...... Manual drive shaft will work with the Auto Diff. The length DOES NOT really matter, I really didn't notice much of a difference on length when they were bolted in there. You could tell a minor difference when laying side to side but not much at all.

The driveshaft has a cricular ridge that you set in the auto driveshaft so It stays aligned. You then just drill new holes and bolt her on. Will work fine till you get the money for a manual diff. Don't be scared to get on it either. I recall numerous street launches with that thing on.

Do you have the manual diff now? If so, how much difference did it make?

I think the spacer would need to be 12mm thick ( the difference of the two drive shafts). You could get the diameter off the flange. And use the flange and drive shaft as a template for the holes.

Just for fun I priced the manual diff flange, it is $98.34 at
Malloy.

Hell I would get the manual diff flange... It was a pain to drill those damn holes in all honesty ;)

And there really isn't a difference other than noticeable RPMS changes, and off of a dead stop.

Was your acceleration alot better with the 4.10s? Or not really much different?
