I have a '86 Grand wagoneer with a 258 six in it. I also have what's left of an 89 G.W. that has an 8 that is blown. The 89 has Dana 44 axles. What I would like to know is, can I bolt an overdrive 627 Torqueflite directly to the 258? If I can't, then what would I need? Any help would be much appreciated.
