30dodgedd6 Posted February 26, 2017 Share Posted February 26, 2017 This like a ford nine inch style carrier but the housing does have a back inspection cover. Let me know if you need pictures of the exterior assembly. Thank you Link to comment Share on other sites More sharing options...
keiser31 Posted February 26, 2017 Author Share Posted February 26, 2017 (edited) The gear numbers are really needed to check on interchange. The number needed for the ring gear is 308281.

30DodgePanel Posted February 26, 2017 Share Posted February 26, 2017 (edited) John, I'll try and post a few pics of Hollanders interchange info to see if it sheds any light for you, I believe you may have a few options from what I seen.

30dodgedd6 Posted February 26, 2017 Share Posted February 26, 2017 I pulled the cover and ring gear ratio 491 #309938 - 2-5-30 Date. (the 3 is questionable in the # ) It all turns nice but the ring has one chipped tooth at the very tip and two have some small pits on back side. The pinion gear has two chipped teeth also at the large side of the gear. Looks like the bearing cage is split. But it all turns nice. I think it was restored in the 60's 70's the cover had a weld so maybe had some work done at one time. it would need new bearings and seals at least. One axle the wheel nut thread is half stripped. This has all the brake shoes etc.. PICS available from my phone Link to comment Share on other sites More sharing options...

The number needed for the ring gear is 308281. You need to know if the vehicle in question was made before April or after April. According to the part number I'd say it's after April but please double check to make sure I'm correct.

keiser31 Posted February 27, 2017 Author Share Posted February 27, 2017 Thank you, Spinneyhill and 30DodgePanel....that is EXACTLY what I needed. I have a set from a 1931 CM6 Chrysler that are marked 309957, so they will work in the DH6. Thank you again. Link to comment Share on other sites More sharing options...
