DII Front Flange Bolts for the Rear Drive Shaft ?????
 

Hi,
On my 2001 DII, I need to replace the four bolts that hold the front of the rear drive shaft to the flange located inside the parking break.

One of the nuts cam off completely and I replaced it with a random nut from the hardware store that had the same thread. One other of the four bolts is stripped and the nut is loose so I can only tighten it so far but not torque it down or it will spin.

So I am trying to find out what size, length and thread these four bolts are so I can get replacements. I believe the head of the bolt and the size of the nut may be somewhat special to fit into where they need to go, aka- not completely standard, but I'm not sure. The dealership wants $7 per bolt and $7 per nut! If I know exactly what I need I can probably get them from the local fastener supplier for pennies.

My plan is to:
1- Remove the front of the rear drive shaft.
2- Remove the parking break housing.
3- Remove the flange that comes out of the transfer case, I believe a 33 or 34mm socket is required for this.
4- With the flange removed the old bolts can be removed and the new bolts installed.
5- Reinstall the flange
6- Reinstall the parking break housing.
7- Reconnect the front of the rear drive shaft.

Can anyone help me with the specs on the four bolts?

Has anyone done this before? Any hints, tricks or cautions?

Thanks
Brian
