Dana 18 VS. Dana 20.

["Joel M Brodsky" <jmbrodsky@xxxxxxxxxxxx>]

Binders, please riddle me this:
Is a Dana 18 any stronger than a Dana 20?
Dana 18s were all twin stick and Dana 20s were Single stick, right?
Is a Dana 18 really just a Dana 20 with a twin stick?
Same shift pattern for a single stick on a Dana 18 as with a Dana 20?
Is the bolt pattern mounting the same for Dana 18 as for Dana 20?

Basically, can I put a Dana 18 in directly where there was Dana 20?

Thanks,

JoelB
