NP435 questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've got an SM465 that I planned on putting back into my 71 GMC. Since its a half ton truck I dont see the need for that heavy duty of a trans. I was looking at the NP435 they seam to be a realy nice unit, nice ratios, not too heavy, direct bolt in. The problem is that I'm having trouble finding one for a GM. I was told they were only made them from 67-72 for the trucks, but I was also told that the NP435 that came in the F_rd trucks will bolt in? I know the input shafts on both are 6.5" long and 10 spline, but the F_rd ones are 1/16" less diamater.
