    1. Hi all,

      I am looking for pretty much everything to attach the rear axle and springs to each other and the frame. I have an 84-88 2wd chassis and rear end. I bought new springs and shocks but I need the bolts to mount the front of the springs to the hangers, the spring pads/plates/brackets, u-bolts, shackles and the bolts for the top of the shocks.
      Thank you

    I wouldn't even bother trying to source used parts on those and just buy some new ones, plenty of aftermarket options for that stuff since it's just mounting hardware.

    Are you trying to put this axle under the 77 pickup? I dunno if I'd do that personally, pretty sure the axle you picked up is going to be a 7.5" differential out of a 2wd truck vs the 8" that was used on the older trucks (and 4wd when those came out). Also I believe the axle WMS widths are different, which may/may not present issues trying to mount it (perch width on axle vs perches on chassis). I don't know enough about it, but pretty sure that's what I've seen in specs of different Toyota axles.

    Here some info for you...

    Axle width:

    73-78 ~ 53"
    79-83 ~ 55"
    84-88 ~ 57"
    89-95 ~ 58.5"
    95-04 ~ 60"


    Wheelbase:

    79-95 Std Cab ~ 103" wheelbase
    84-88 X-cab/ std longbed ~ 112" wheelbase
    89-95 X-cab/ std longbed ~ 122" wheelbase


    Rough offset guide:

    7" ~ +30-35
    7.5" ~ +35-40
    8" ~ +40-45
    8.5" +45 and up.

    Later axle on early truck will mean relocating spring perches. All early trucks (pre 4x4) came with standard 7.5 r&p rear axle. Toyota did make a 3/4 ton axle used on special use chassis’s such as motorhomes which came with an 8” r&p. The ID plate under the hood will show “GO82” if it’s the heavy duty axle.

    You sure? I always thought all the previous gen 73-78 had an 8" (my 75 is an 8" with 4.3 gearing) Not sure about 68-72 Hilux or the Stout though but I'd guess 8" as well. When they came out with the 4wd that's when they gave the 2wd trucks the 7.5" unless they're the HD purposed trucks

    Positive. I did months of research on Toyota rear axles. Unless your ID plate says “GO82” you have a 7.5” r&p.
    Another way to tell is the 7.5 has unequal length axle shafts. When ordering, you’ll see they always ask if you need drivers side or passenger side axle shaft.
    8” has equal length shafts. Can be used either side. Also, 8” axle shafts are no longer available, even aftermarket. It could be a hd axle was added to your truck later by someone else.

    Not to sure about that, I put the rear axle and springs from a 93 into my 1980 Hilux, apart from the driveshaft flange it was a straight bolt in. The 93 was a stronger axle but bolted in the same, from memory there was something different about the spring shackles I think I had to use the 1980 version.

    Yes, mines a G102 on the ID plate - 8” with 4.37 gears. I know I’ve seen several others mention their trucks also had G-code axles in build threads I’ve read over the years, so I assumed Toyota didn’t start using the 7.5” until 1979

    good to know on the rear axle shafts availability

    You were lucky somehow. The 1993 frame is much larger than the 1980. Spring perches are centered on each frame rail. Maybe you picked up enough slack with the shackles to make it fit. As long as it works, you’re good.

    You might be right. I only researched 2WD commercial vehicles 75-78. Seems like there is an 8” with 4.37 gears. My bad...... The GO82 runs 4.10 gears.

    Hell, I squeezed a GM 14 bolt 10.5 ring gear full float axle out of a 2500 series into my 1978 motorhome. Anything is possible.

    Ok I took some photos 1993 frame is 1050mm wide at the axle which is the same for the 1980 frame please ignore the diff in the frame it is from Nissan and just there so I can move it around the yard.

    The rear shackle mount is 80mm on the 93 and the shackle has a dog-leg bend in it where 1980 is 70mm and is straight.

    here's a photo of the 93 diff installed in the 1980 the housing is somewhat lager than the 1980 note the new wheels 9 spoke alloys from a ford falcon. 93 diff is a 4.1 the 1980 is 4.3.

    Now Im thinking that I also had to change the lower shock mount to the 1980 version as the shocks mount differently but it was still a straight bolt in apart from the driveshaft flange which was a case of re-drilling the holes, the recess in the flange is the same just pop the 80 drive shaft on the diff and turn 45 degrees and re-drill the holes.

    I’m impressed. First hand is better than the manuals. I’m never too old to learn something new. Great job!!!!
