74 Duster project

Well I have a nephew who lives in cali and visits for the summer each year. He's been trying to talk me out of one of my mustangs, but they don't get run hard anymore. I picked up a 61 falcon and the guy told me I had to take a 74 Duster with it. A little gas and a hot battery and she fired up. Slant 6 running on five cylinders. Well I drove her to the house and he adopted it. As it turns out I happen to have a 70 fury wagon on the north forty that drove when I parked it their about 2 years ago. The idea is to use the wagon as a donor car for the Duster. I hadn't even climbed under either one yet, any ideas what I need to keep my eyes open for. The wagon has a 318. I was thinking 318 bottom end 360 smoggers that I would have to chop the heck out of, 727 out of the wagon. Is the rear end or front end even close. I'd like to get a head start before he gets down this year. Might as well get the wagon up to the shop and start measuring.
