I think member Mot can help you with the clear lenses. Here is his profile:

I believe you will find the consensus opinion on castor correction for the 80 is that it is beneficial after 2" of lift and getting essential after 3".

I run a 3 inch mandrel bent system on my 2H turbo and it is great. The 12ht would love it. The press bent system can lose up to 20% of flow area in some bends so go mandrel 3 inch for sure. Clear tail lights are available on ebay also Mot sells them.
Re the 4 inch lift this is illegal in Queensland so unless you are moving south of the border you are stuck with a 2 inch lift.cheers

Sanda , what do you need clear tail light lenses for?
I thought only the 4 cyl toys used them.

Try Ebay for the clear lenses. I saw some on there they were $157 I think that was for the pair. They were im Melbourne.
This is an input from Slee offroad that you might find useful:
From the Slee Off Road Web Site:
By lifting the truck, the front axle moves away from the frame. Due to the design of the front control arms, the axle will tilt forward and reduce the caster angle. Stock caster for a 80 Series Land Cruiser is 2-4 degrees positive.
There are also some that do not install the bushings due to reports of cracked front housings or arm mounts. Indeed this has happened in the past, but we believe that it mostly happened in Australia where the driving conditions are a lot different from here. Also, this might have been from earlier OME bushings where the center metal sleeve was a lot larger and the polyurethane a lot smaller. We have not seen a single case of this in any of the trucks that we have serviced or installed the bushings on. We have seen cases where the center metal sleeve has separated from the urethane.
Caster can also be corrected by some DIY ways of slotting the mounting holes and welding washers on the outside. This accomplishes the same as the caster bushings, in that it rotated the axle back to stock location. The problem with this is that you are limited in the adjustment you can make, and if done to severely, the tie-rod that runs behind the axle, will hit the front control arms when the suspension articulates. This can result in a bent tie-rod or your steering binding up.

We are aware that a lot of people do not install Castor correction. Mostly this is due to not having the right tools to do the job. They are then convinced that their trucks handle ok, but they are not aware of how good it can handle. We have installed the caster bushings for a lot of customers, that ran the truck without it for a while, and I have yet to meet one that did not comment on how well the truck drives. now.sleeoffroad said:
Here is a drawing on how caster changes with lift. The drawings shows the locations of the frame mounted bushing and the two front bushings. The axle center line is shown, as well as the caster angle. The axle was set at 3 degrees positive caster at stock height. The axle was then dropped 2" and the new caster measurements are shown.
We initially estimated about 1 degree of caster loss per 1" of lift. This was from installing different lifts on vehicles and then having the caster measured. Due to a lot of variables involved, this was not 100% correct. From the above you can see that 1.7 degrees of change per inch is more accurate.
Also, when you measure the traditional "2 Degree" bushings from Old Man Emu, you will also see that they actually correct closer to 3.3 degrees. So they are still the correct adjustment for a 2"-2.5" lift.
Our caster plates yield 8 degrees of correction and the current control arms we sell are 11 degrees.

thanks for all your advise.. i asked RACQ insurance to see if they still covered the 4' lift and they and no worries with it, but wheather or not it is legal i better do some more home work.
. i think the clear tail light will not be happening any more!
BIGBROWNDOG did they still squish the tail pipe over the chassis or can you go under without dramas?

I've got a Turboed HZJ80 with a 3" mandrel bent exhaust. The exhaust has plenty of clearance over the top of that rear crossmember. The heat sheild needs to be removed but I haven't had any dramas from excess heat. Give Beaudesert Exhaust a ring thats where I got my system from. It is a very well made system that bolts together with flanges and has a good flex joint. I've got the system with a muffler which sounds OK but my mate with a 3" pipe on his HDJ80 runs no muffler and his sounds sweet. I might have to get a straight pipe to replace my muffler one day.
The legalities of the 4" lift in QLD is a bit of a grey area. The law at the moment says you can increase wheel travel by a third so if you limit the wheel travel by some means the lift is legal. They don't usually measure this though just the bumpstops clearance so bumpstop spacers might be OK.
Up here in Hervey Bay I haven't been hassled about my lift but I have heard of Brissos getting hassled on a regular basis.
Castor correction is definitely required for a 4" as well as panhards.
