Very good ..
two conflicting opinions.
and thanks for the Link ....bit spendy at 600 bucks....
though ..
I do note that FAS says something about their dry ice fitment process
for the ring gear,
that tells me they are getting the hardened ring gear separately from
the flywheel that they machine....
probably.
I'll just heat the ring gear up on the one I have and see what happens.
the comment about the ring gear being hardened and the flywheel not so
much makes perfect sense.

I used to take them to a machine shop for replacement, but here is a fancy new flywheel option for you: http://www.foreignautosupply.com/parts-accessories/34-in-line-4-cylinder-vanagon-engine-conversion-flywheel/#.VyvP4vmDGko

Gone are they days, as far as I know, that you could restore a flywheel by grinding through the teeth until you could just knock the ring off with a hammer, then put the new ring in the oven and the flywheel in the freezer and then take that leap of no return. Fun!
