I bought a 3.90 for this very reason for my 47. I never used it though, as I'm switching to a more modern axle.

Your lack of preparation is not my emergency

Use the forum search. The forum search is below the "post new topic" and "post new reply" graphics near (but not at the top) of the page.

oldblu49 discussed it - search for his posts

Basically, I realize the exterior modifications that are required, but I wasn't sure if there were any internal issues other than exposed inner axle bearings. | | | | | Joined: Dec 2003 Posts: 2,953 'Bolter | | 'Bolter Joined: Dec 2003 Posts: 2,953 | R.F. you can use the center section from a TF axle in the AD housing. This way you can keep the existing e-brake linkage and won't have to worry about spring mounts. BUT you will have to set your pinion angle and then weld the pivot pins on your spring mounts so they no longer rotate or twist. I have not yet done this but have the necessary parts courtesy of Bill at red58. | | | | | Joined: Mar 2002 Posts: 553 Shop Shark | | Shop Shark Joined: Mar 2002 Posts: 553 | Go to the "Engine & Driveline Shop" Forum and type in "3.38" in the search. | | |
