Well, I've found the JE prefix to be 3.42 ratios in the past but that isn't a promise. Not at all a common ratio for a pickup in the 1950s so I'm immediately suspect. My guess is 614 is a production date. It doesn't match any of the data I have here.
Sorry...I failed to answer your other questions...there are no direct bolt-in rear ends I'm aware of however if you can find a rear end from a late 1960s/early 1970s Chevy or GMC pickup the width should be okay and the 12 bolt rear ends came with a large number of ratios. The one I'm using is 3.07.
