It should all basically bolt in. Depending on the radiator sizes/opening sizes on each, a little finessing may be necessary. Trans linkages (you didn't say stick or automatic, I'll assume automatic) should swap, possibly may need a little creativity there, too; depending if column or floor shift. Or if they're both power or manual steering (the columns differ in length). It's all in the details, but the major assemblies just get unbolted from one and bolted into the other, at the risk of sounding oversimplified...
