Wanted: 31 Model 8-87 oil pump drive gear

Anyone have the drive gear for the oil pump shaft where it engages the cam for a '31 344 ci? The interchange manual shows the "oil pump gears" are the same in 60's and 80/90's for a couple years, but I took one out of a '32 60 series and it's only the internal pumping gears that are the same. The drive gear is different. Egge had one in stock, but when pulled from stock it was corroded and unusable. Any of these out there?
