Rear Diff

well....I had a 8 3/4 that twisted the housing...it was not braced in our 71 Dart. It now has a Dana 60 basically cause the ring gear had some chipped teeth also...so money wise yes the Dana cost more up front...but should last that car for the rest of its life...

take two

71 duster with only a year of racing on it...twisted the housing...no back bracing...I bought a Moser FAB 875 cause the 3rd member is pretty new and wanted to get some use out of it....

the 8 3/4 is going to have ring and pinion problems sooner or later...I think the smart thing to do is just replace the R&P ever so many years and don’t wait for it to break....

If that ring gear broke with you were in 1st gear...better check the sprag in the trans...especially if it a 727...otherwise it will go boom....
