Flywheel for Magnum

Bringing back a thread since I had a similar question.

So.... is American Powertrain the ONLY source for a steel 5.9 Magnum flywheel that will bolt up to my 833 4 speed?

It has to be 130 tooth and 10.5 inches right?

I am most likely going carburetor only so I do not necessarily need the tone ring, so I wondered if there were other vendors out there that supplied the steel flywheel without the tone ring.

Also, I'm assuming that a flywheel for a 5.2 and a 5.9 are different? I guess that's something to watch out for.

Thanks!
