Hi All, I currently have a NP445 in my 73 W200 with a 318 and a divorced NP205. The NP445 is just the close ration version of the NP435. I am going to be swapping to an NV4500 to gain an overdrive. The transmission I have is a 97 chevy short tail shaft 2wd trans which has been converted to a dodge 10 spline magnum style input shaft. I'll be using the hydraulic bellhousing setup from a 1995 small-block magnum ram. Questions:

Will I be able to reuse my flywheel if it's in good shape?

If I need a new flywheel, are the magnum 318's internally balanced like my 73 motor, or are they externally balanced like older 360's?

Looking at replacement flywheel's and clutches they seem to be available in 11" and 12". Will both sizes fit in the stock bellhouing, and if so which one is better to use?

Does anyone have any pictures of the tranny crossmember used in the 1992-93 NV4500 trucks? Will this work with my short chevy tailshaft? Or am I better off just fabricating something?

Thanks,
-Jon
