where are you sunnygirl?

theres a 5sp on gumtree perth apparently rebuilt for $900
weekend1000 also has one for $850

I bought mine off him, nice guy to deal with.

If you want to try to get some more life out of your 4sp, supercheap and repco sell an additive by Nulon called G70
I have had some success with this

Hi guys,

A real late reply i know, since last i put another 4 speed in as it was all i could find and barely afford at the time didnt even check the model it was a really rushed and slack buy on my behalf.

Unfamilia you have a point there i realize now the old box was very sloppy from the get go and smashing through gears definetly didnt help the situation! Its a stock A15 engine at the moment not sure what model the gearbox is i think its a 56 but i may be wrong.

Thanks for all the feed back i will definetly consider a 5 speed (and all the bits and pieces to go with) at some point as i intend to keep the 120y and do a full resto once i get back to work and settle in my own house.For the mean time im thinking about attaching a webber not to sure on the model but i have a mate that has a spare off some sort of 1.8L motor.

Also i have considered (down the track) fuel injecting the weber can anyone shed some light on this?

120y wagons are awesome, I would buy a 5 speed if you are thinking of keeping her as she will like cruising better with an overdrive. She will always keep her value been what it is and not a Hyundai excel so its up to you.
Diff wise the 3.7 H150 is quite rare in Oz and the 3.5 and 3.3 non existent and command around 300 USD from the USA. Then you have to have it fitted and will cost halve of a 5 speed and then you can just use the 4 speed 60 series box but they are rare too in good condition.
Someone I think Bige was selling a datsun 60 series 5 speed with all the goodies and I think Nick might have sold his Toyota t50 dellows conversion also or not selling anymore?.

True !! I'd even advise her to go new HD clutch kit, like a Vanette, for extra $50 and dont forget to machine the flywheel.. Just incase you decide later down the track to throw a weber on it etc etc. Dont just think the cheapest quickest solution. It's not over kill, it's just like insurance. Do it once , do it properly.

Oh for sure, but they are harder to find now, also need to re jig the gearbox mount and file down the edge of the tab on the clutch cable.

She might of had a 60 series that went bye bye. Too little info and too many variables still

Well for the same price or a tad more, i'd go 60A and be alot more confident and do it right the 1st time

A 56a does too as long as your not launching like a drag racer every set of lights. Lasted years behind My a15 no issues ever

Make sure it is a 60A 4 or 5 spd box not a 56. The 60A will handle an A15 no probs

I don't think a long highway run would kill a gear box after 1 week, so either it was on the way out it driving style possibly (hard shifting burnouts and other abusive driving styles )

Need to know car driving style and other associated mods. How did the gear box break? Symptoms noises?
Id just get another 4 speed see what happens.

After anges box breaking runs in his race car and ended up being pinion angle between.diff and box.

If it says 56 on it, it is not overdrive. All the other A-series 5-speeds are overdrive including 63A and 60-series. But they look a lot like the four-speeds.
