Gears, Transmission
For those of you that run LT77 5 speed defenders,I came across these numbers in some of my catalogues.some of the UK military rovers with the 2.5litre N/A diesel engines had lower ration 1st and 2nd gears.I don't know of the availability of these,but I'm sure Dave Ashcroft may know of a source if Genuine Parts cannot help.

FRC 8860N    Gearbox assy   x1   51A prefix
FRC 3412       Drain plug - gearbox
FRC 6690       Gear 1st speed
FRC 6691       Gear 2nd speed
FRC 7600       Gear layshaft cluster

I don't know if you need the complete gearbox assy or if you can just change 1 & 2nd gears and the layshaft,but according to my bible the rest of the box is as per a civilian type.enjoy

Idler Pulley (A/C)

Size should be 42mm OD, 15mm ID, and 17mm wide/thick [approx] 
Press the old bearing out and press the new one in, then re-stake at the factory stake points to keep the bearing tight in the pulley. The shoulder bolt is a slip fit in the ID of the bearing.

ILCO X184 B65 (GM)
O2 Sensor
You need a M-12 sensor, that is, metric 12 by 1.25 threaded. The Lucas 3LS, heated titania sensors are made by NTK Technical Ceramics, apparently the *only* manufacturer in the world now doing the 12X1.25 size. These are the *three wire* sensors used on OBD-I and previous vhicles. Try any of the
following Nissan parts: 226A0-40U60, 22690-88G01, 22690-61A00 or 22960-M210. All are made by NTK and differ only in the terminal plug. Oh yeah, they differ in price: the Nissan one is around $60.

Now if you have the OBD-II system, you need a *four wire* sensor. My crossover number is Nissan 22690-85E10, though I haven't tried it yet. The best price I've found is around $77.

NOTE:  Center door hinge on body side has a support plate to span across uneven surface.  It also has a nut welded to the lower position so a nut is not required there.  I replaced the factory spanner plate with a custom stainless one that is 1/8 thick.  It also does not incorporate a welded on nut in the lower position so it uses a nyloc just like the other positions.
