Ok I posted this once before but never really got a straight answer what alls needed other then the motor? The truck I want to put it in is a 93 k1500hd with the 14 bolt rearend and nv3500. I will be keeping the trannsmission and if it blows it blows. The donor truck is an 83 or 84 k30 dually. Will the radiator out of the dually work? I imagine Ill have to make my own brackets of some sort.

I would vote a GMT400 radiator, so try and find a GMT400 that is either a automatic, or rotted to hell, because if you find any GMT400 6.2Ls with manuals, you should be kind enough to send the link my way! lol but anyways, try and find a GMT400 diesel (93 and older will have a cap and a overflow bottle, 94 and up will have a surge tank with the cap on the surge tank.) that you can swap the cooling system over, the after that, it is a matter of getting the right mounts, and doing all the wiring. that will be the biggest issue. luckily, you can skimp here, as it will be a fully mechanical setup, so you will just have to have toggles and push buttons to control glow plugs, lift pumps, etc.

You'll need hydroboost brakes since a diesel doesn't produce enough vacuum. Obviously need a tank for diesel fuel since the 1500 is a gasser. You'll need new fuel lines, an electric lift pump, frame rail mounted just like the stock ones are. Stock 6.2 has a mechanical fuel pump but the boss can be blocked off and should be as the mechanical ones aren't very good. I don't know much about the transmission you choose to use. I'm not sure if you'd need a stronger flywheel and clutch or not. Not even sure if the transmission will hold up to the added harmonics of a diesel.
Radiator should be gracious big enough to cool the diesel. As long is it's a big block that the radiator previously cooled. It's critical that diesels stay cool. And an engine oil cooler would be good for the 6.2 as well.
Good fuel filtration is critical in keeping the injectors and injection pump in good running order. That should not be skimped on.
How good of a 6.2 diesel is it? Do you have any information on it? That would be much appreciated in helping you.
