I have found already that it is hard to find sources for parts as I am in the states.
I own a 1985 BJ70 Landcruiser I live in the US, mine is a 3B I assume from your posting this is the engine you have.
I have not found it difficult to find or purchase parts, just a little more work than a standard vehicle.
I have a full copy of the Toyota fiche (for 10 different Landcruisers) which lists all parts for my rig, I would recommend you get one. It helps when you know what the part numbers are. I have called Toyota USA given them a part number and they could get it for me, on the same part I have had Toyota tell me they could not help when I ask them to look it up.
I have a complete set of parts drawings (these are a must have item), they are invaluable in all aspects of purchase and repair.

With the ability to source your own part numbers there are several good parts sources.
1. NAPA, has some parts at good prices, I sourced a water pump, ac compressor, alternator brushes, filters, thermostat.
2. Toyota it self both in the US as well as Canada will help, I have gotten alot of parts from them, you do need to find a parts counter person who will be willing to order Canadian destination parts, I have found one and it really helps.
4. G&S cruisers,
G&S Cruiser Parts I can't say enough about them (Sheldon is a good man and a friend), they are great.
5. Dave Stedman Toyota 4X4
Japan4x4-Export stedman@japan4x4.com he is on mud, can't thank him enough for all his work, sourced for me the AC evaporator box to install AC in my rig (BJ70 Canadian destination, very hard to locate), can get parts that will amaze you.
This list is by no means complete, it is just my experience, most all Landcruiser people are good people and willing to help, hey they own Landcruisers, they share a common disease.
If you put in a little effort, contact people in the above list, you will find it far easier to get what you want or need.
I should have mentioned MUD as this is a great source for all kinds of info and parts.
If you need help send me a email
jake2far@hotmail.com I will help you with part numbers, advice (for what its worth) and sources.
Good luck with your project.
