changing diff from single to dual wheels

[Worzel]

that makes sense,
Did it have LT tires?

had light truck tyres,thought they were in good condition,plenty of tread but then the back on it is quite heavy ,really over weight with singles about 300kgs over;;;mike

I'd measure for yourself if possible, plenty of times i've been told something will or won't fit .

Don't assume anything....

If the diff will fit between your rails then your away,
You will need to widen the arches and the inner arches (as ben said.)
Changing the spring mounts on the diff isn't a huge job but get someone qualified to do it..
assuming that the spring mounts on the diff can be moved to the width of the rails

Or sell it and buy another one, but then you're passing on a problem to the next guy, which some people can do and i always struggle with

seems like to much trouble have to leave it as is and drive carefull
