theres bin loadsa discussions about the diffrences between the valver/willy box.
i was told , after my rebuild that all teh gears are slightly diff. and that the diff etc is also a lot better than teh valver variant. hence gettin the re con was so expensive. reno no longer sell gear kits etc for the willy box, i needed new layshaft etc etc etc, which had o be machined.
diff ppl have diff opinions, but general concencus is that the willy box is same as valver 1st - 4th with 5th being slightly taller.
but like i say the guy who built mine says they completely diff. 1st -5th, with 1st -4th bein a slight closer ratio than the valvers, and 5th longer
