How much headache would it be to swap my 46 4-Speed Crash Box for a 50's SM420? I have access to a SM420 and would really like to get rid of the old Trans next summer. What is the model number for my 46 4-Speed? I've looked and looked and the model number has alluded me. My truck is a 1.5 ton.
Thanks

I'll call Carters tomorrow and ask Jimmy if they still have modified bellhousings for a SM420 in a 46 1.5. Does anyone know off hand how much the front shaft must be shortened? | | | | | Joined: Apr 2005 Posts: 242 'Bolter | | 'Bolter Joined: Apr 2005 Posts: 242 | Call me I can help you about changing your 4 speed trans. 1-262-392-2989
