StephenB, I've been there. It can be done without much pain but there are some things you MUST do. I see your retired so you have the time. Plan it out, put it on paper and then decide.
....if you want take a look at my photobucket for pics of the steering/powersteering, motor mounts(those are the easy part) and so on. If you have any questions drop me a PM.....oh, but I didn't have a running driving vehicle!! Far from it!!
