I ain't never heard of grinding the teeth of the gears! and I can't believe G2 would say that. I didn't do my gears myself, but had the install instructions when I bought them and mine are Genuines (now G2), and it said to notch the pin. Or maybe it was the install sheet for the Auburn that said it, I can't remember, but I do remember it said to grind the pin...

here are the two email responses i received from G2, excluding their names.
1. Hi Jonathan,
In many cases it is necessary to grind a tooth or two to get the cross shaft
back in the carrier. What you will need to do is grind the inner part of
the ring gear directly in front of the cross shaft hole on the carrier, not
the whole tooth but where the shaft makes contact. Some people say to grind
the actual cross pin but we don't recommend it as it makes the pin weaker.
The ring gear has plenty of teeth on it and the grinding of a couple of
teeth will not affect its strength. If you have any other questions fell
free to let us know, Thanks
2. Hi Jonathan,
Due to the thickness of the 4.56 gear of the Chrysler 9.25" application,
some material will need to be removed off of the ring gear. This is to
allow clearance for the cross shaft, and is done by grinding the tip off of
a couple of teeth on the ring gear. This will not affect the strength of
the gear in any way, as long as your mechanic does not grind too far into
the tooth contact area.
Either way, all the information from you guys has been more then helpful. Thanks

Look here......http://www.ringpinion.com/TipOfTheDay.aspx?TipID=7
So Randy's Ring and Pinion do this as well.
I've also got a reply from a company http://completeoffroad.com who make a "notched pin" as well.
Read here ......
Dear sirs.
May I please enquire if this pin is necessary to install 4:56 gear set in the rear of my vehicle stated above?
I have at present 3:55 stock gear set in place but upgraded the stock Dodge lsd a while back with a Detroit True Trac.
Also, do you ship to England?
Many thanks for your help in this.

Yes, you will need this pin. Also, we do ship to England. The cost of shipping is $15. If you are interested, we can send you a Pay Pal invoice just provide us with your Pay Pal email address.
Thank you,
Complete Offroad
So to answer RedTruck-VA;s reply, to fitting gears to a DTT rear and not needing a "notched pin"......I'm in a bit of a conflict now?
I suppose this company wants to sell it's notched pin......but would they really suggest buying this if it wasn't necessary?
Sorry for a bit of a Jack to this thread.....but I think it's all good info about this issue?

CHRYSLER
PROBLEM: CHRYSLER: 9.25", 12 Bolt Cover, 4.56 and Higher.
I bought 4.56 gears for my 1/2 ton pickup, but I cannot get the cross pin into my carrier.
SOLUTION:
It does not matter whose gears you use. You will need to modify your cross pin to use a 4.56 or higher gear in your vehicle. This applies for open differential, Auburn and Eaton differentials. The pin will need to be cut at an angle opposite the bolt hole. Because every manufacturer is different, no measurement is provided.
