Ok so, I have to find out if the NV4500 flywheel will work with my 360, or see if I can find an aftermarket one that will work with both?
I want to use my bell and not have to put together a hydraulic set-up.

Getting a drive shaft built here in farm country is no big deal.
Done it before.

I am just asking questions to see if anyone knew what will swap.
I haven't counted out the O-A833 or the A518 yet either. Summer is still a few months away. If I have to spend very much $ I will throw in something I have laying around here. i.e 727 and move onto another project for the time being.

I don't have a 340. I posted a link here in another members post.
