Likely older than you were told. The cast iron transmissions were the NP435, looking like this:OLD HEMI said:The trans is a cast iron case, it is out of a 1/2 ton 4x4 with full time 4wd. It may have been newer than I was told but no way of knowing because it was crushed. Thank you for the info. I guess I will look for somebody to swap a 4x4 trans for a 2wd.
