diff ratios?

[chris_g]

hi, new here
ive got a '67 lwb ex german fire dept, and a scrap '75 twin wheeler for spares
just wondering if anyone knew the diff ratios for a v6 twin wheeler, or even if
the ratio is bigger then the v4's ratio, just want it to be a bit more user friendly,
on the motorways as im going to be using it to tow my car to show,
ive only just got it registered and its a bit horrible at 50mph or more

welcome to the club just come back from transitmania @ 45mph

have you got any pictures of your firevan

oh and in answer to your question you have a 5.82 i think you can get a 5.1 ish(cant rememebr exact) but the prize diff is the 4.63 (best you can get in a twin wheeler) but if your towing you might be better off with a 5.1

v6 twin wheeler uses 4.63 but has overdrive gearbox for the extra speed lift, as previously said there are 3 ratios, 5.83 5.14 4.63 you may well have the lowest one 5.83 if its v4 and german built as being a fire vehicle it could have been built for city only or on site use where top speed would have been secondry to its weight pulling (water tanker) and sprint capability
