If they have a specific flywheel you need to buy those parts that fit that flywheel
If it is an aaz you will have a 210mm clutch and the mk3 style with one post in the flywheel. The earlier has 2 posts that locate the clutch. If you are buying ALL new pieces it should not matter in a regular car, but since it is a westy I have no clue. If they have a specific flywheel you need to buy those parts that fit that flywheel.
No prob and GL! Just in case there might have been any confusion, pull the tranny and leave the engine in the van
