Thats a good idea Lurch, but probably not the simple solution I am looking for at the moment  :P

I doubt I'll be doing that SR conversion anytime soon so I have nothing to lose by getting an L series box.

Paul from Zbitz is suppling me with a box that he hasn't restored yet for $150, I'll use the bits I need and give him what is left over. I thought it was a decent price.

I'm gonna call the seller and ask him to pay for these extra costs incurred on his "rebuilt" box

cheers for your advice guys! I'll let you know how it goes

Picked up the box from Paul today, was a 280zx box but that shouldn't be a problem as we are only using the rear part. It selects gears perfectly. Specialist is getting both boxes tomorrow and hopefully will have all the good parts in my 260 box by next weekend. If that can be done then theres a good chance this time next week the Z will be back in my driveway  ;D ;D

Took a quick video to demonstrate the difference between the 'fully rebuilt' box from Perth and the 280zx box I will be using to replace some of the parts with.

Geez the 'rebuilt box' looks pretty rough.  Bet that would be as fun to drive as having malaria.  :P

I'd be fitting the 280ZX box complete as is, Steve.
It looks to be in reasonable working condition.

Keep the Perth box for spares...

Hey Lurch,

Yeah we did consider that. The gearbox specialist opened it up and basically told my mechanic that it has been rebuilt, just not in the rear (where the parts that are worn to bits and affecting the selector are housed).  He seems to think that the selection issue will be easy to fix by just swapping over that rear section, or something to that effect.

Also have to remember that the 280 box could go anytime, as it has never been reco'd.

Gearbox went in on the weekend, got the car back yesterday afternoon and I have mixed emotions.  :-\

I got the flywheel machined, clutch master and slave cylinders reconditioned, new flexible hose and spigot bush, gearbox oil replaced, rear main oil seal (supplied by genuine nissan for 55) replaced.

Total cost of the job ended up being approximately 750 (parts and labor), added onto the cost of the dodgy gearbox that I sourced. My mechanic said it drives beautifully apart from a slight whine in the gearbox sometimes, which is caused by the person who reconditioned it doing it wrong.

I drove it last night when I got home from work, I couldn't resist, and my mechanic was right. The clutch was very smooth, gears were moderately easy to find and it felt like I had envisioned, except for one thing. It whines like a 2 week old baby all the time in 5th, and varyingly in the lower gears. :-[ When I give it a little bit of speed it sounds like a blowoff valve.... in the gearbox.... ::)

Overall I will just have to learn to live with the sound as I can't afford to be changing gearboxes again... I really need my car to get to uni. I guess I'll know what its like to have fully sick turbo sounds for a while  ;D

Doesn't sound like a reco'd box at all Steve...

Maybe you should have fitted the 280ZX box instead.

You are probably right Lurch, but then again I should have paid the 900 to get a reco'd box here in Brissie done with some kind of guarantee...

I've gotta give Paul (zbitz) the rest of the 280 box back anyway...

I'll probably look at buying another box next year when I have some time to work on it. Really though, it's just a little noise and the box performs quite well.

Thanks for the advice everyone. If there is one thing I have learned about gearboxes its that it pays to get the work done yourself and pay a few extra bucks to be sure that the box you are buying is in good condition, rather than relying on the word of a 3rd party or seller.

I hope someone else will read this and avoid making my mistakes  ;D
