Can any one tell me the difference between a drover box vs sj50 vs sj70
I have all 3 at the moment I have the drover box in the zook but am finding at 100k it is on 3400 revs and will only do it down hill
How many revs at 100 are others zooks doing and will they stay at 100 comfortably?

Drover is early SJ50.
Later SJ50's and SJ70 had same 1st through fourth gears but a slightly taller 5th gear ratio.

Thanks want33s
I was told the driver box had the higher 5th gear but when I put it in I didn't notice much difference, at 100k how much higher will my sj70 box be?

I think the difference works out to about 100rpm ... SFA.
