Sorry, forgot to mention crucial info which is that as of now I have access to an M46 equipped parts car.
So with Anthony's flywheel, I'd just have to get a new clutch as well as any other seals, bearings etc that must be replaced with new ones.

Radness! Lots of winning

Yes, except from a monetary perspective!

I bought a $300, 440,000km manual 240 that was written off. I just swapped all the manual parts over - Clutch, clutch bolts, flywheel, gearbox, tailshaft, pedal box, clutch master, lines, etc, etc. If you do all the work yourself and don't mind using second hand parts you can do it for cheap. I have had zero issues so far. I also used a bunch of other handy parts off the car.
It will take you a solid weekend of work - one day to take everything out of the 2 cars, one day to put everything back in. The only special tool you need is a torque wrench, a few socket extensions and a Bentley/Haynes manual.

Bring me the car and i can change the trans(swap autos) in 3 hours for 3 slabs of beer/cider
$600 to swap an auto in a 240 is a rip off

@Samman88 you make it sound easier than others have... I don't feel confident to do it myself, I'm by no means a mechanic, I just like doing DIY stuff when I can on my car but I've not ever pulled a transmission or anything. If I can find someone that could help me along the way though that'd be good, so I could save money on labour costs AND learn along the way.
And the other problem is, that the pedal box would need to be swapped over which I'm sure would be a pain, and there's no hole in my firewall for the clutch cylinder either.
@Philia_Bear thanks for the offer, if I can figure out how/when to get to Sydney I might take you up on that. (Any chance that you'd do a manual conversion for me for a lot more beer and/or money? worth a shot!)

Time issue on the manual conversion
It's about a full day instead of sub 3 hours
240
Yeah no worries, that's what I figured.
Can a used, working M46 be counted on to work OK for a while or is a reconditioned one worthwhile during a conversion?
Anthony
M46 boxes are very strong and normally you would bank on them being good (or good enough), but depends of course on how many kms the donor unit has and therefore condition of syncros etc..
The attached overdrive is always the unknown - being good, not so good, to bad - or has an issue that can be solved without dismantling like the relay soldering in models from 81 onwards (no relay in earlier models).
Forget sourcing a reconditioned unit (unless your a fanatic), if one is stuffed you look around for another (best with a gearbox attached as it can be an issue separating them).
I once threw good money and time into an old overdrive to try and get it right. Wish I hadn't, but it was 100% leak free in the end. Lesson I learnt was to obtain a known good unit.

OK thanks that's pretty much what I figured.
And even if an OD failed there'd still be 4 gears which are better than an auto!
I had another chat with Total Traction and he seemed to think that an autoelectrician would be needed to wire up the OD, is this correct? How complicated is it?

Not really as you have an od relay already.

Easy as heck
The wiring you already have from the overdrive on the auto can be reprovosioned for the od on an m46
Anthony
Wiring is one aspect you really could do yourself after the mechanical parts are put in place by a shop.
Especially when you have a parts car to follow the lead on.
Wiring diagrams are out there (you have them already)
PS. I have a near brand new OD relay you can try if yours is suspect.
So essentially you can narrow down their job and save some dollars. This way the onus of the OD working is not their responsibility.
240
That sounds like a much better plan.
He also suggested a new clutch fork and new pivot bolt, is this worthwhile? Clutch fork is quite expensive... if it's not too much of a risk to reuse the old one then the whole thing could be affordable, just.
Anthony
Good advice - As I live in the same city .... my spare car has both near new, plus the clutch and ground flywheel the but is you have to remove them ( ie tailshaft then gearbox). Have Volvo receipts and all.
Alternatively the best idea is If you get the car removal bloke to pick up the car and take to your place you can remove them it at your leisure. Only has rear wheels, the front can slide on round bits of wood.
Best to take any other discussion on the above offline with me.

Slightly confused as to what clutch I'd be after.
I understand that the LH2.4 flywheel I will have to use a clutch to suit, say for a 1989 model. But will that clutch still work with an M46? (As it would have been intended for an M47)
Or is a clutch for a 740 turbo necessary?
Spac
There's basically two main variations for 240 clutches:
1. Coarse spline (first few years) vs fine spline (most of them);
2. Flat (early, pre-86 IIRC) vs dog dish (late).
#1 is determined by the gearbox, #2 is determined by the flywheel.
The only time you'd have any sort of drama is if you had a very early gearbox with your LH2.4 car. Otherwise, it's just a matter of working out what you have and ordering the correct bits.
The clutch fork is a potential thing. Like everything, have a look at what you have before committing to spending money. I've got a decent spare if you need it.
240
I'll have an M46 from 1985 and an LH2.4 flywheel. So what I'd need is a fine splie dog dish flywheel - that right? (Or do I need coarse spline?)
Just trying to figure out how to get one - they all seem either advertised as for M46 or M47 - presumably an M47 one will work? Because it will be right for the flywheel, and should have fine spline?
Clutch fork - I won't be able to see what it's like until it's too late, ie until the mechanic has pulled it out and is about to install it in the car being converted. @Spac Is your spare newish or just known good 2nd hand?
Spac
All clutches to suit dog dish flywheels will be fine spline.
My clutch fork is good used.
240
If I go ahead with the whoole thing I might grab yours as a backup if it's ok?
Although are aftermarket ones any good? New aftermarket is only $40 at IPD.
this is what FCP comes up with for a clutch to work with a stepped LH2.4 flywheel
Can I therefore assume that it'd be fine with the 1985 M46?
Sorry about all the questions, just want to make sure it can go smoothly.
