which tailshaft for a ke70 wagon

[Golberg]

Have some more info for you now too:

Just did an EPC rummage

33103-20130
33103-14040
33103-14041
33103-12130

Those are all the part numbers for T50 extension housings from all TE72's (even as early as 1979), AE71's & AE86's. Each is the substitute for the one above down the list. Suggesting that they are all interchangeable. And the 1979 boxes were definitely 20 spline, so I don't think that the spline count has any effect on the extension housing. As such I'd say its a pretty safe bet that an AE86 extension housing will go onto a TA22 box with some messing around and interchanging of parts.

wow I had no idea. However wouldnt the shifter rods and all that need to be changed? if anything I would need to put the guts out of a t18 box into a broken ae86 t50 right?

[Golberg]

Well a T18 box already has the correct shifter location, so you should only need an A series bellhousing.... but an A series bell isn't a direct fit to a T18 box, people have done it before and reported mixed results. From memory the problem was the front main bearing is different between the early and late T50's and as such you have to leave some piece out of the early T50 front bearing when you swap the bell (or come up with another idea).

Ideally the best solution would be to use an early T50 rear shaft (with 20 splines) and then put it into an A series box... but I have no idea if that would actually work, hazard a guess and say no, but if you compare the part numbers of the syncro's and bearings it might shed more light on it.

But ultimately, its a big fuck around just to be able to use a KE70 tailshaft rather than an AE71 version. One has to question wether its worth it rather than just finding the correct tailshaft.

[Sam-Q]

yeah I hear you and point taken, thanks for the help

[Golberg]

Had another thought again (I'm full of them tonight it would seem).

A wagon would be pretty easy to do an F-series diff convo on.... Find a YR22 Tarago, steal the diff, you wont need a huge amount (if any) custom mounts made because its just leaf spring.

Then use the usual T-series tail shaft options.

[Sam-Q]

well if I can just split the shaft life the guys have said then I wouldnt need to do so as I dont care about LSD's or strength too much

what ratios do they have anyway? I am always up for a new place to find a diff center for my ae86

[Golberg]

There are heaps of different F series ratios, they've come in so many different cars, common in the front diffs of 4WD hilux's, through to MA61 supras, cressidas, hiaces, taragos, the list goes on, you could more than likely get any realistic ratio cheaply and easily.

Splitting the uni wont work either, even if you do that, you'll need the front split off an AE71 shaft. Might as well go for a whole AE71 shaft.

[Sam-Q]

my bad I got mixed up, I just need a complete ae71 tailshaft as they also have the S series right

[Golberg]

Well yeah, you want a complete AE71 tailshaft, but its not an S series in it, its a borgwarner diff. But all AE71's & KE70's sold in Australia had a borgwarner diff apart from the panel vans and the Spirit AE71.

[Sam-Q]

ok I thought it was the other way around? well anyway I did run a pano diff in my ae71 wagon a long time ago and i adapted it by getting the pinion lightly modified to suit, the differences are fairly small. This would only be needed if I was to use a panel van tailshaft though and the chance of that happening is almost zero.

Curious any idea which one is stronger the borg warner or the S series? I know I blew both of them up with each behind my old 4ac in the past
