at least now im almost on the re-build instead of the dismantle
thanks for the box i.d.
one other question i forgot to mention, not so long ago one of you clever bunch told me how to check diff ratio. I may not have done it right but its an LSD and one wheel hub turned once and the propshaft turn 1.75 times approx. is it that simple i.e. 1:1.75? or is there another calculation?
