Correction: checked my log and I actually have a 35 tooth speedo gear.

Thanks Steve. I'll keep an eye out and see if something comes up.
Otherwise, I'll just have to live with some new gears when I get the diff
locks! :-)

I found some links on the net and for 31 or 32 inch tyres with 3.07
gearing, I'll need a 27 tooth speedo gear. With 33s, I'll need a 26 tooth
gear. This ofcourse will change again when I regear. The only bummer is
that we have keep our speedos calibrated to pass local Warrant of Fitness
requirements (safety checks). Good thing is, speedo gears are cheap.

Well, I am in New Zealand and TJs exported to our local market all had rear
Dana 44s. I have the build order and it confirms its a Dana 44. I have
matched the shape with photos on the net, its a Dana 44. Now for the
gearing, well I thought too that Dana 44s came with 3.73, but I have done
the tyre rotation test and it works out to 3.07. Also, the label on the
pumpkin says 3.07. So does the build order. Thus, I believe my statement
is correct. This may be a weird combination, but that is how they were
sent to the New Zealand market.

Thanks for your reply. It must be a Jeep thing....
