i can't get the old drill bit out as its in pieces, but even worse, i don't know where to get a new one or even the proper dimensions of what I need to buy to replace it.
if anyone knows the dimensions of the steel pin, that'd help a lot. also if you know where i can find one, that'd be great too.

Im guessing if somebody put a drill bit in for the lock pin that the bore it rides in has gotten pretty chewed up. You may want to look for a whole new carrier from another axle to get that part.

Sounds like a bag of worms. In the Chevrolet, that "pin" I believe is actually a long hex headed screw. Could someone have broken the screw off, and in an attempt to maybe drill it out, broken a bit off in the hole?
If you put bearings and seals on, it means you must have removed the "pinion gear shaft" (looks like a king pin) to access the clips in order to pull the axles....right!
So now I'm not sure what's going on. Unless GMC uses a pin, this should be a small bolt. It really sounds like this has been broken, and then attacked with a drill. Clean the hole with brak-kleen, grab your trouble light and magnifiers and see what's going on.
My picture shows this as a blind hole...not somewhere you usually drive a pin into! I don't know the size, but I will bet someone on this site does..maybe wrenchbender...keep your fingers crossed.

any information on what should go in there and where i might find it would be appreciated by me and my wife, who can't get her van back into the garage until i fix this!
:-)
happy new year

If you had the pinion shaft out you should be able to remove the broken piece from the shaft & make shure the hole in the carrier is clear & if the tthreads are usable. My partner is going down to his salvage yard this week end. He can probably find one & send it to you. Reply or e-mail me [email protected] & I will give you his phone # George

thanks much to everyone for your help on this. as usual, it turned into more than the simple project i envisioned, but its definitely a learning experience and fun too.
happy new year to all on the board from the mcgowan family!
