Default Magnum engine with NP435?

I was doing some searching on google about Magnum engines to earlier Dodge Np435 transmissions and I found this site:

It says what I thought, in that the Dodge 5.9 bolt pattern has not changed between LA and Magnums. It also says that you need to reuse the Magnum flywheel.

Has anybody here done this? If so, what clutch and pressure plate did you use?

I ask this because I'm wondering if the 11" flywheel from a Dodge Mangum & nv3500 combo has the same pressure plate spacing as a Dodge LA & NP435 combo? It would seem so based on that thread since they just say reuse the flywheel, but I'd like to confirm this.

I know the NV3500 and the Dodge NP435 have different input size and spline configs, so it's a matter of finding the right combo of parts. I'm hoping that I could keep the Mangum flywheel and then just buy an LA-engine based Np435 clutch disc and pressure plate.

I thought you went with the 4.7L anyways??? Did you change to a 5.9L now? Anyrate, sorry I can't help you with that. I would think that as long as you use a 11" clutch kit to match the flywheel than you should be fine. Just get a disc that matches the input shaft size and spline count and you should be golden. I would think anyways...
I would say call advance adapters or novac or something and ask over there. They should be able to help you out with an answer. Good luck and post back here what info you come to find out as I am curious as that could be an option for me as well.
