I have a Jeep friend that will give me Dana 70 axle from a Ford truck. It has a tag number with the 4:10 gears I need. I want take it completely apart and check the axle spline size. I have an 81 CJ-5 with a Dana 60 I purchased in the 90s from Summer Brothers. I am going to call them but anybody know who can cut and narrow the fullfloater housing for 1 piece axle with flanges for Jeep backing plate and axle shats with 5 on 4-1/2" circle? Want to replace my original dana 35 before it breaks with chevy 350 motor and 12.5 x 33 x 15 tires..
