Update: Thanks for all your help guys! It's back on the road. His installer put the new gearset into the old third member because the filler plug plug was in the axle housing on the car and in the third member on the truck. Other than that it's all good. Really appreciate the guidance. Tim

Thanks guys. Its going to the installers this week. I'll let you know how it goes. One issue is going to be a filler plug. The car had it in the housing and the truck was in the third member. The installer figures he can drill and tap a hole.

Hi guys. Thanks for all your help so far. And sorry to Rockwood for getting your name wrong. We got the rear end out of the car and the tooth count is 39 and 10. We're gonna run with it because it looks good inside. Does anyone think there will be an issue with spline counts or carrier bearing size? I've read about the A and B carriers and the non interchangeable crown and pinions but the plan is to put the entire third member into the truck housing. Just looking for reassurance. Thanks. Tim

Couple of teeth broken off the pinion gear. I suspect that after 70 years the gear oil was mostly gone. I wan't in charge of maintenance.

Hi Rockford. The truck is a 2nd owner survivor. He's had it for 25 years and I don't think it's done more than a 20 mile round trip in all that time. He's well aware of its limitations and quite content with them. I understand what you're saying but in this case I think the 410 will be fine. Hopefully the car one is good when we get it out. You should see this truck. Original right down to the paint and hubcaps. I've driven it and it feels like its 2 years old instead of 70. Thanks a lot. Tim

Thanks dpollo! That is exactly what I wanted to hear!

Thanks so much for your help on this guys. We may have a new plan. I've located a 47 Dodge special deluxe nearby. Rockwood - You're saying we can install this third member into the truck housing? With no spline count difficulties? What axle ratio is the car likely to have? Thanks again, there 's a wealth of knowledge here!

I have had stuff shipped up marked as antique farm tractor parts and kept my company name out of it. It has worked out. I don't have a problem paying as long as I'm 99% sure I'm getting the right product. Seems to be very limited info on these rear diffs. Young Ed: I could probably convince him on the 373s but there is hardly anything from the forties left around here. Thanks for the suggestions guys, and keep them coming.

Hey thanks Ed. classicnosparts.com shows 4 part numbers on the listing 1567835, 6673661, 664392, and 1192394. I presume they are supersessions. The 664692 jives so it looks like i'm on the right track with this one. I really appreciate your help! If anyone has a supersession list we could make sure. Thanks very much. Tim

We're looking for a crown gear and pinion gear. I should be able to get the seals and bearings locally. I'd just like to see if the 1567835 is the right set for the truck. Thanks, Tim

Thanks Casper. Looks like it got moved. Sorry I'm new at this.

Hi. First time poster here, hope you guys can help me. i have an auto parts store in Canada and a customer needs a new crown and pinion for his 47 half ton. Unfortunately he has re assembled it so all I know is it is 41 and 10 (4.1 to 1). There is a number cast on the outside of 1115941 with an A in a circle. The inner seal is 1126007 which crosses to a CR 14423. A company called classicnosparts on the interweb has one with a part number 1567835 which their listing says will work. I have to be careful with shipping to Canada because of freight and customs charges. Does anyone have a parts book for this old girl to make sure I'm on the right track? It's a model FL1-16, serial number 90042087. Probably Canadian production so these numbers may not make sense. Thank you very much. Tim
