i'm changing my 64 to 4x4 right now. I didn't like the way it set on the 86 frame i had so i took the suspension and moved it to the 64 frame. They are right it is alot of work, but luckly I'm a fabracator by trade so it's a little easier for me.If all you want to do is upgrade brakes and things they are right, just get some new model stuff or after market. I hope you have fun building your ride, that's what it's all about.
