No reason not to have a 14bolt out back. It's the strongest you can put in there short of a rockwell 2 ton unit. As for the front, they never made a 14 bolt front axle. 1 tons had D60's, 3/4 ton's had 8 lug D44's up to the late 70's then switched over to the 8 lug 10 bolt. Both are adequate with reasonable tire sizes depending on your intended use.
I've wheeled over a lot with a D44 on mine. I'm not into full blown rock crawling and I'm careful not to overly stress it to cause breakage. 35's is about as big as I want to go with my lift and my intended use. Comes down to what you want to do.
