    The new avatar looks cool Peter. I'll have to get around to doing the R32 front brake conversion and writing it up. I have all the parts now but have been too busy to drill the spacer and put it all together. Hopefully I'll get it all done before Toyota Nationals. Good write-up by the way, I'll be using this for my rear conversion when I get to it.

    The Hilux axles are certainly beefy units. I got mine back today, along with the backing plates and axle flanges. I am ready to redrill the backing plates to fit.



    Hilux flange (hub):



    [Images deleted as requested]

    If you can use one of the two pre-existing holes I assume it is the one I have marked. This means that to drill the other three holes requires a small part of the metal flange (marked) to be ground away. Is this correct? Have I got it right? Does this impact on the strength of this part of the backing plate (that holds the handbrake mechanism on the reverse side?)

    Assistance would be appreciated as I have to finish this and return the axles for re-pressing on the new bearings, etc.

    Cheers,

    Peter

    I should've looked more closely at Allan's photos but I think until you have the plates and stuff in front of you it's hard to visualise what to do. But Allan's photos clearly show the section I've circled as having been ground away without any adverse effects on the backing plate.



    So I think we're good to go tonight with the grinder.

    Cheers,

    Peter

    Thats correct Pete.
    Also, the stud near the ground away section will have to be quite long (longer than hiace ones). It has to go through both sides of the pivot pin support and the caliper bracket.
    I just used one of the original xA70 ones on each side.

    Cheers

    it also looks like it was re-welded along where it was ground away no?

    Now that you point that out - yes, it does.

    Probably to hold the bracket in place.

    Thanks,

    Phil,

    When I took the axles out I compared the Hiace studs I got from Pick'n'Payless (1990 model Hiace) with my original Hilux ones, and the Hilux studs were about 3mm longer.

    Thanks,

    Peter

    Hmm Not sure.
    Mine is an RN41 diff, as is GT's.

    I just checked my original studs, they are approx 36mm in length.
    The Hiace type ones I required were approx 42mm.

    So you might be ok, but wont know until you dummy it all up.
    Just assemble at all onto the diff temporarily (minus axles) and you should be able to see if they're long enought to go through it all.

    Did the brackets arrive today?

    I'll go with whatever works best.

    Caliper brackets arrive last Friday morning. Already got them painted up and test installed.

    I'll dummy fit everything tonight to see how it all goes together.

    Cheers,

    Peter

    I see that in Allan's photos that the two studs protruding from the MA70 backing plate have either been removed or cut down (probably the former):



    they are obstructing the fitting of the caliper bracket. Are they just punched out and replaced with a small nut and bolt?

    Cheers,

    Peter
