You might have more success looking for a complete rear axle.
Maybe I missed something. Do you already have a new ring gear? If the pinion is worn I would expect simialr wear on the ring gear. Running a new pinion on the old ring gear will probably only work for a while.
The part number listed is correct for a 4.11 gear SET-ring and pinion. The poster is in France so probably some language conversion issue. That gear set also list for 37 and 38 1/2-3/4-and 1 ton trucks. Perhaps someone that has changed their truck rear axle may have a good used one.
I viewed that same item and have emailed the seller questioning if it is for a master or std and he replied he has both,. I am waiting to see if there are ANY numbers on the parts to identify them. The red flags are already up as he listed only as for a 36 Chevrolet - said he has both std and master . At least it's an Ebay listing so there is a process in place if not correct to get a refund even though the ad says no returns.
He replied that they had a family parts and scrap yard business for 90 years and the info he is supplying is what the box is marked. I still asked for numbers on the parts even though they are probably not OEM and who knows if the parts are in the correct box. Seeing that they need to go to France all the info we can get is best.
I looked at ebay but I've never found what I expected. I think this part is really difficult to find ... Thanks for telling me if you have any contact.
I agree the one pictured in the Ebay ad is for a std . I used contact the seller feature as the ad did not specify and he replied he had both and would get some numbers today. If that does not happen I have to assume he did not find a correct master gear set. Following is a copy of the Emails. Newest reply at top.

Your previous message I prefer the numbers on the parts if any .
dun_1946: We had a family owned 4 generation parts store and salvage yard for 90 years. The boxes are marked with application. I can take a picture of that for you.
Your previous message Looking for a set for a Master for another person. Are there any numbers at all on either part? How can you be sure of application? Item will need to be sent overseas so want to sure it is correct and will then advise buyer to purchase direct.
dun_1946: I have both master and standard. No not have the GM part numbers
Your previous message Is it for a Chevrolet Master or Standard?? Any numbers on either part?? If so please list. TY

Several years ago I made 25 sets of these (equal to the 602476) in a 3.36:1 ratio (37/11). My research at the time led me to believe they fit: some late production 35 Master cars. They fit 36 Master cars and 1/2 ton trucks. They fit 1937-39 1/2, 3/4 and 1 ton trucks. Most sales, of the ones I produced, were to 37-38 1/2 trucks, several to 36 Master cars and at least one for a 36 1/2 ton truck. Only problem as far as actually fitting was a 37 Panel truck with a Canadian differential requiring some machining to get it to fit. (An easy fix would have been to acquire a 37 USA rear end ). It took me 15 years to sell them, so not a real fast, high demand market. FYI, the Republic Gear aftermarket # is H1463. Nothing on eBay right now but sometimes these aftermarket sets show up for sale not referencing the vehicles they are made for.
triZero, I have a NOS ring and pinon set for a 36 Master in 3.82 ratio. This set was made by the "Service Gear Corp". Do you know if this ratio was available as a special order from Chevrolet or was this an after market ratio?
triZero, With the increased popularity of pickup trucks, in our hobby, There would probably be more interest in your gear sets today, that there was back then. Price is certainly a factor but in some cases, the availability of CNC capabilities has made stuff like this cheaper today than it was years ago. I'll bet you could get advance orders and deposits, if you were interested in making another batch.
