i was didnt think this thread would turn into an arguement!cheers for the input anyways lads.
ive been offered a 7.5" diff at a fairly good price so i think im gonna take it,ill have more peace of mind with it in place,im convinced the 7" diff isnt up to the job on its own.

will a granada beam fit?got offered one for free yest off a mate.

@tabetha
ive given him back the diff to see what went wrong,i honestly dont think its failure was any fault of his,i'd say the viscous coupling just collapsed or sheared,he's fairly well known as regards fixing diffs,i wouldnt have much reason to doubt his workmanship.ill try and get a free check over of the 7.5" diff off him before i fit it thou...
