just trust me from experience man it wont hold. put it this way, my 3/4ton chevy 4wd that came with a 6.5 diesel, i put a cummins in, and it smashed the front end down like a foot.
just do some reading on it, everyone that has done these swaps will agree that it wont hold up on a dana 44 or stock springs. you are going to need to reinforce your steering box on the frame as theyre already prone to cracking the frame. the weight of the cummins will make it that much worse.
you are probably going to need crossover steering as well if you dont already have it from lifting your truck.
and again id be worried about frame strength on a short box 1/2 ton truck. these motors produce massive amounts of torque, and can twist your frame if you get on it. just some advice for you

A big block chevy is about 700 pounds and a cummins is 975 so yes u are right it does weigh more so maybe I will add a leaf in front but I will wait till I have the motor in

As for the frame I did the steering box already and I do have plans for the frame I also have a sm465 in my backyard with a 205 would that bolt to the getrag besides the shafts having different splines?

no the bellhousings are different. they make adapter plates but theyre really pricey. id recommend just finding a good getrag for it with the transfer case with it is a must. the 29 spline np205's are nearly impossible to find on their own. that way everything would bolt right up and work no problems.
