I did a Nova subframe about 17 years ago. dumb, dumb, DUMB.
Don't do it. Trucks with car frames are not fun.
I'd use the stock suspension and steering. Upgrade everything. That's what I'm doing on my 3/4 ton. It has a small block chevrolet mounted between the framerails hooked up to the original SM420 trans with a late 50's V8 bellhousing. Looks pretty stock.
