pinion gear chipped

[hihoss]

I have discovered that the corner of 1 tooth on my pinion gear has a chip/chunk out. I found the remnants in the bottom of the housing. there is no damage to any other gears. In that I have not yet driven it I don't know if there was any noise or how long it may have been like this. 
Finding a replacement, I have been told, it going to be a challenge. Any thoughts on repairing it, or filing the edge and let it be?

 

the part numbers are as follows;

 

drive pinion 314961
drive (ring) gear 314958 (confirmed from the gear) 
ring and pinion matched set 543276
whole assembly 314841
4.66 ratio

I was able to get the part number from the ring gear and the book gave me the other numbers to go with that gear. 

Unfortunately I have the truck on stands to renew all the brakes and too close to the wall to get a slide hammer on one axle to remove it. So until I get the front wheels on and can move it over safely I do not have the diff out. 

I appreciate any help and advice.

Do you have or access to a Hollander interchange book?

What are you working on? Any junk yards near by?

It is possible to grind the broken edge and continue using your truck until a replacement can be found.  I had a bearing failure that took half an inch off the end of all my pinion's teeth.  The differential shop ground the jagged edges off (no guarantee) and I drove for three years before I found a good used C&P.  I built myself a complete carrier assembly as a spare and it is still sitting in the shelf until I get either enough time, ambition or have to change it.  This is on my daily driver.

[hihoss]

I do not have an access to a Hollander interchange book.

Its a 1932 dodge depot hack. on an f10 chassis and drive train. Not something I would expect to find in a junk yard. I have been search the web and so far not had any luck. 

Thanks

I was just told My pinion is bad so I am now actively looking for a ring and pinion set for the above 1932 f10. 4.66 gears. 

Is anyone aware of a shop that can repair gears?
