J-H First Gear Overall Ratios (1st gear ratio times final drive ratio = overall ratio)
First ––– Top Gear
10.76 –– 3.45 = J-H stock 4-spd & JH 5-spd 3.45:1 final drive ... (Ufdah 1st)
11.33 –– 2.69 = Toyota W58 5-spd & JH 5-spd 3.45:1 final drive. (Ufdah 5th)
11.63 –– 3.45 = J-H 5-spd car, stock 3.45:1 final drive
11.64 –– 3.73 = J-H 4-spd car, stock 3.73:1 final drive
12.25 –– 2.91 = Toyota W58 5-spd & JH 4-spd 3.73:1 final drive.

I've not driven a W58 with the JH5's 3.45:1 final drive ratio, but the 2.69:1 overall 5th gear would be a really tall cruising gear. I have a hard time imagining that being practical for the stock 2.0 liter 907. 'Maybe' in the flat lands, but not in hill country. Or maybe with a 2.2 912, or a 2.5 hotrod. Something with some torque.
