Dana 60

I would not use the Dana with 3 1/2 tubes. Thats the HD one for trucks which has a lot more webbing that adds up to a lot of extra weight and they don't make 3 1/2" Mopar car ends that size. You should look for the 3 1/8" tube Dana found in older trucks and vans. I have several Dana 60 parts that I will be selling soon. Let me know what you need. Note: because most suregrip units for 8 3/4's are over $400, a Dana 60 is less expensive to build.
