I use a GTR Torana shock I modified and some stainless steel bottom pins and urethane bushes
 
Bit agricultural but thats all I could find at the time
 

thought it would be useful to some people to know that datsport can get adjustable konis for a 1000 front end they have them for the rear aswell.. also as far as the rear is concerned datsport offer kyb exel g (factory spec) however, baz said that he would be able to get kyb gas adjust shocks for the rear but would need a few orders to make it worthwhile.. 
It all depends onwhat you want from your car but i just thought i would share my findings.

RatB10 is using 1200 rear shocks in his 1000.

Also the Pedders part # 3029 listed for a 1000 front shock also has a listing for mini moke and mini front shocks.
I believe Dundee1000 has mini shocks in the front of his 1000.

Here is a link to a mini moke web page with some compressed and extended lengths shown.
http://www.mokesinc.org/index.php?topic=7616.0
As far as i can tell the mini ones will compress around 5mm further than a 1000 one but are not as long as a standard 1000 shock so might be good if lowering your 1000.
(Would a shorter extended length reduce body roll?)
 
It looks like maybe rears can go too? but lengths are slightly shorter like the fronts. Has anyone tried this?
It would definatley open up some aftermarket options if they fit.
A mini weighs much the same as a 1000 so mini shocks seem like a good substitute.
Mini's have a little more of their weight % distributed over the front wheels so for a heavier engine swap into a 1000 the mini shocks seem like a good idea.
 
EDIT.
 
Leith, The ones I gave you were a full car set of rebuilt original nissan ones
If you want to spend $300 each you can do anything you want...

Leith, As a completley random idea... how about using a clamp around the shock and just mount at any height you want from the side.
Make something like what's in the pic below, but instead of the bolt mounting point have a tube/eye to mount rubbers into and fit it to the standard lower mount from your leaf spring mount.
 
You could use almost any shock length you want, if you lower your car even more in the future just slide the mount along your shock and retighten.

 
I would suggest a large clamping area if you were to try this as I don't imagine the shock manufacturers would have had this in mind when designing their shocks.
 
Or remake your lower mounts something like this

Thats a pretty good idea, after looking at the bottom spring plates on the rear of the sunny, 120y and 1000
its amazing how much smaller the 1000 ones are. Would be great to swap to the stronger later ones.

well story is i was sposed to have a pair of these weeks ago! i would of sent those down to you but at the moment im waiting on my mate to get back to me with a price because shipping from USA is just way to expensive end's up costing $100 a shock, but seems he's useless has either forgottten or doesn't care....
 
But i might of found another option for the rear, the bilstein shocks we use in the race cars are also pretty short but a bit fatter. so on friday im going to try fit one up and see how it goes, we've got boxes of them and they come with a wider range of dampening settings, are alot easier to get a hold of and are only $80
 
but here's the part number for the shock i was talking about bilstein ak105, i think there sposed to be for a mini. if you can find somone to import these cheap d let me know
 
edit - i was getting them off summit, but trying to get them from qld bilstein dealer for cheaper shipping! i'll get onto him today

didn't think it warranted a new thread BUT has anybody had any bad experiences with running too stiff a gas shock?

Neil any chance you can make a run of the SS pins for the rest of us?
group order

the home use CNC milling units are coming!!! just a matter of time 
 
home made hubs, pistons, rods, pins, badges will be possible

any chance you'd be able to get the part number off the shock body?
