Is a passat 16v Flywheel (037105273c) the right flywheel for a vr6 clutch conversion?

Time to change transmissions in my 00 Golf. I want to upgrade the clutch, flywheel etc at the same time, and have acess to a flywheel, part # 037105273c, which is from a passat 16v. before I go spending the $ on this flywheel, I wanted to make sure it will work with a Stock vr6 clutch, like this one http://www.mjmautohaus.com/catalog/product_info.php?cPath=2_4_18_237_1968&products_id=3

Also, what's the best transmission fluid to use?

I would call them and ask them . On that clutch kit it says it will fit that flywheel but the best thing is call them and ask them.

Use OE dealer fluid.
Here is my post about manual transmission fluid:

That Flywheel will be fine.
