    I've been trying to find a straight answer on this today, but I can't seem to find much concrete. Well, maybe there is some, but then every time I find another source it contradicts. From the mud forum it looks like Aisin lockable hubs with part number 43530-60042 should fit my 1994 Land Cruiser, but then if I do an internet search on that part number it says that they are for '95 and later model of Land Cruiser.

    Can anyone confirm if the part number above will fit my truck? Build date is Feb. 1994.

    I came across that as well, but then I found this:

    http://forum.ih8mud.com/threads/part-number-for-80-series-aisin-hubs.473144/

    Followed by this:

    http://forum.ih8mud.com/threads/7x-8x-aisin-manual-hubs.449578/

    Indicating that it should fit up to mid '94 80 Series, but there isn't anything from Aisin confirming that. Some 80 series had part time 4x4 but maybe they weren't Aisin's? According to that Aisin link there isn't anything that fits '91-94, but maybe they just didn't make anything for Toyota over that time? Confused...

    Also wondering if one of these would work:

    The birf's are different on early trucks vs. later, your build date is VERY close to the cutoff so be careful with that. The difference being a groove machined in for the selectable hubs snapring to lock into that is absent on newer trucks. Maybe run your VIN in ToyoDIY to confirm which birfs your truck shipped with. Here's a thread where Beno confirms that part # hubs should be direct fit for your truck:

    http://forum.ih8mud.com/threads/aisin-hub-conversion-how-to-thread.782550/

    I had a set of hubs from the HDJ81 I parted out I was planning on using on my truck "someday", but lost them in the garage fire along with everything else. What's the reasoning for wanting to do this? Most opinions on MUD are that if you don't have a selectable TC you're still spinning 90% of the front driveline even with the hubs disconnected, so you won't see much in the way of improved fuel economy, but it will exhibit RWD characteristics with the hubs disconnected. You'll also NEED a CDL button if you don't already have one (not sure if all HDJ's got this, but FZJ's didn't).

    Seems odd that the Aisin part number says it's for '95 and later, but based on that thread the longer birfs of that time would need to have a goove machined in and for the earlier versions it would be a direct fit, but Aisin doesn't even note that it fits these ones? Odd...

    The main reason for doing this is to reduce wear on the front end. If I get improved fuel economy, that's a bonus. I had my front end rebuilt just under 200k kms last Septmeber and now 30k kms later it's already leaking a bit again. I'm hoping by doing the conversion I can go further between rebuilds. The last one lasted from 114k to the 200k service. I don't know why this one didn't last too long.

    Also I hardly get off road these days and going forward I don't think I'll get out as much as I used to. Therefore 95% or more of my driving is around town and I don't live in a climate where winters are bad, so I think I'll get more benefit from the switch than leaving it. As you mentioned the hubs alone isn't a full part time conversion. I plan to have it fully converted to part time. I was looking at the Mark's kit and you can get it with Aisins, but I'm looking at about $1000 AUD shipped for that. Expensive, but maybe that's just what it's going to cost me.

    Yup, I have CDL button.

    I'd see a lot more draw to a part time conversion if I didn't live somewhere with winter 1/2 the year, I like having full time AWD for that reason.

    Does your truck have the newer dash, or is it still the same as the '90-/93's? Or was it '95 that got the new dash with the airbags?

    In North America, only the FJ80's got the CDL button, it wasn't factory equipped on the '93+ FZJ80's.

    Older style dash unfortunately. I've had the face off way too many times for stereo and switch related items. Would have been so much easier with the '95 style.

    I don't think the dash changed until the '95s when they got the 1HD-FT. I suspect the birfs would have been changed to the longer ones at this time as well which wasn't until July '94. All other info I find says it happened after April '94. Maybe that was for the North American market. To me it wouldn't make sense to change parts for just the last few month of production, but maybe they did.

    Birfs would have changed whenever they ran out of old stock and had the new ones on hand, unless it's a PT truck from factory there's no difference at all from Toyota's point of view.
