    just my luck!, I bought a scrap 55 for parts, turns out its got 3.70 diffs, I wish I knew the code #05 for that before i bought it. :doh:
    I dont get it though, the truck is labelled as a 2/78, the frame # makes it a 9/77, but its got 3.70 which I thought came out 1/79. It's got the Weaker Birfs though (I checked and compared against minitruck ones) AND the higher gears (which are stock, its stamped on the build plate), I was hoping for the rare fine spline 4.11, guess I flew too close to the sun. Was 3.70 an option you could request? Now heres a question, since i have such a messed up truck I wonder if i have course spline 3.70, I'll have to report back on that one.
    P.S I'm in Canada (maybe thats my problem) :slap:

    hmmm my 78(forget the build date) has 4.10's.

    the KK at the end of the model might be a clue, not sure if thats a US model....it prolly is, I'm not as hip as I should be on 55's ;)

    AFIAK no you could not order different gear ratios(in US at least)

    well from the landcrusier FAQ (which i shoulda checked first)
    In the model # FJ55LG-KK, the first K means 4 speed, and the second K means Canada.

    Could it possibly be that someone has swapped things around before you took ownership??

    according to the VIN plate, the axles ratio that it came with is 05=3.70.

    but I suspect its a canadian thing as well. I don't have much info on the canadian stuff, what i have is early 70's

    My catalogs show 3.70 gearsets for Canadian vehicles starting in February 1976 production. It also shows a change-over to 3.70 for US market vehicles starting in Jan 79.

    No cause the 3.70 code (05) is on the identification plate

    Your talking for 55's right, that would really suck if my 76 FJ40 had 3.70's
    Well, wish I knew that before, I guess you learn something every day, I wonder why they did that?

    possiblely because canadian 40/55(and 45, but these did have 4.10) didn't have the same(or any) emission crap that US spec cruisers did, so they had more power, which ment they could run 3.70's a bit easier and might get better milage and for sure a better highway speeds, as well as being quiter, only thing they loose is a bit of low range. This is just a pure guess on my part

    I might be interested in the 3.70's if you're going
    to pull them as complete pumpkins.

    The cataloging indicates that 45's kept 4.11 gearsets.

    so I checked the code plate on my 76 fj40, its March and has the #05 code, I've been wrong all this time, so now i got two sets of 3.70, I guess I'm in the market for 4.11's now :p

    Dingo,
    I e-mailed you earlier. I've got a 2/76 production FJ55 produced for the American market (4.11 ratios I assume). It still has American registration even! I would be willing to swap pumpkins plus some FJ55 parts that we are needing if you're open to that :). I'm just across the water from you in Greater Vancouver. Model number is FJ55LG-KA, axle code is K082.

    that would expain why my canadian 1978 fj45 seemed to have lower gearing than my canadian 1976 fj40. i thought they both had 4.10s
